|~ siDTHIS IS A PROGRAM TO HELP YOU LEARN TO CONVERT FROM ONE UNIT OF
DMEASURE  IN THE METRIC SYSTEM TO ANOTHER UNIT, JUST AS WE WOULD
@CHANGE FROM INCHES TO FEET OR FEET TO INCHES IN OUR SYSTEM.
HERE GOES.
 HERE'S YOUR FIRST QUESTION:
2WHICH IS LARGER, A CENTIMETER OR A DECIMETER?
D(TYPE C FOR CENTIMETER, D FOR DECIMETER OR N IF YOU DON'T KNOW)
D
YES, THAT'S A GOOD START.
N
 OKAY, MAYBE THIS WILL HELP.
NO, LET'S SEE WHY NOT.
DA METER IN THE METRIC SYSTEM IS JUST A BIT LONGER THAN A YARD IN
OUR SYSTEM.
<HOW MANY FEET DOES IT TAKE TO MAKE A YARD IN OUR SYSTEM?
3
RIGHT, LET'S GO ON.
NOPE, IT'S 3 REMEMBER?

@DO YOU KNOW HOW MANY DECIMETERS IT TAKES TO MAKE ONE METER?
4(REMEMBER, EVERYTHING IN METRIC IS BASED ON 10)

10
2RIGHT, EACH DECIMETER IS ONE TENTH OF A METER.
FNO, THERE ARE 10 DECIMETERS IN A METER, JUST LIKE THERE ARE 3 FEET
IN OUR YARD.
(OKAY, LET'S REVIEW.  IN OUR SYSTEM:
*                   12 INCHES = 1 FOOT
*                    3 FEET   = 1 YARD
"HOW MANY INCHES ARE IN 1 YARD?
36
:FINE, INCHES ARE SMALLER THAN FEET SO IT TAKES MORE OF
THEM TO MAKE A YARD.
DSORRY, THERE ARE 36 INCHES IN ONE YARD.  12 INCHES FOR EACH OF 
THE 3 FEET IN EACH YARD.
4WE SAID IT TAKES 10 DECIMETERS TO MAKE ONE METER
8HOW MANY CENTIMETERS DOES IT TAKE TO MAKE ONE METER?
100
@RIGHT.  EACH OF THE 10 DECIMETERS HAS 10 CENTIMETERS IN IT.
6TO REVIEW:            10 CENTIMETERS = 1 DECIMETER
2                      10 DECIMETERS  = 1 METER
2                     100 CENTIMETERS = 1 METER
.NOW, LET'S GO BACK TO OUR OTHER QUESTIONS.
FNO, IT TAKES 100 CENTIMETERS TO MAKE UP A METER.  THEY ARE SMALLER
<AND EACH OF THE 10 DECIMETERS HAS 10 CENTIMETERS IN IT.
TO REVIEW:
2                  10 CENTIMETERS = 1 DECIMETER
.                  10 DECIMETERS  = 1 METER
.            SO   100 CENTIMETERS = 1 METER
WHAT IS 6.9 X 10?
69
RIGHT AGAIN, LET'S GO ON.
690
6NO, YOU FORGOT YOUR DECIMAL POINT IN YOUR ANSWER.
$NOT QUITE, TRY ANOTHER QUESTION.
	NOW FOR ONE MORE.
(WHAT IS 120/10? (/ MEANS DIVIDED BY)
12
.GOOD, NOW YOU'RE READY FOR WORK IN METRIC.
SORRY, TRY ONE MORE.

HOW ABOUT THIS ONE:
WHAT IS 11 X 10?
110
THAT'S FINE, LET'S GO ON.
DNOT QUITE.  I THINK YOU NEED MORE HELP IN THIS AREA.  PLEASE SEE
"YOUR TEACHER FOR WORKSHEET #1.
HOW ABOUT THIS ONE?
WHAT IS 230/10?
23
$OKAY, NOW LET'S LOOK AT METRIC.
<YOU SEEM TO NEED MORE HELP WITH THESE.  PLEASE SEE YOUR
TEACHER FOR WORKSHEET #2.
BIN THE NEXT FEW SECTIONS I'D LIKE TO SEE HOW WELL YOU CAN WORK
>WITH CENTIMETERS, AND DECIMETERS.  JUST TRY YOUR BEST AND
BIF YOU HAVE DIFFICULTY THEN WE'LL WORK ON THE IDEAS TOGETHER.
ARE YOU READY TO CONTINUE?
 (TYPE Y FOR YES OR N FOR NO)
Y

OKAY.
4PLEASE SEE YOUR TEACHER FOR FURTHER INSTRUCTION.
HERE GOES:
.HOW MANY CENTIMETERS ARE IN 7 DECIMETERS?
70
FINE. GO ON.
DNO.  THE CORRECT ANSWER WAS 70.  LET'S SEE IF WE CAN UNDERSTAND
WHY.
0HOW MANY CENTIMETERS ARE IN 12.9 DECIMETERS?
129
RIGHT.  TRY ANOTHER.
"NO.  LET'S WORK ON THIS IDEA.
0HOW MANY DECIMETERS ARE IN 240 CENTIMETERS?
24
GOOD.  JUST TRY ONE MORE.
>SORRY. THIS IS A LITTLE DIFFERENT TYPE OF PROBLEM.  LET'S
TAKE A CLOSER LOOK AT IT.
0HOW MANY DECIMETERS ARE IN 195 CENTIMETERS?
19.5
<TERRIFIC.  YOU HAVE JUST SUCCESSFULLY COMPLETED THE TEST
:PROBLEMS FOR THIS SECTION ON METRICS.  PLEASE SEE YOUR
2TEACHER FOR INSTRUCTONS FOR YOUR NEXT COURSE.
BYE.
<NO.  SORRY.  MAYBE YOU GOT CONFUSED BECAUSE 195 IS NOT 
8EVENLY DIVIDED BY 10.  LET'S WORK ON THIS A LITTLE.
<TO REVIEW:  WHICH IS LARGER A CENTIMETER OR A DECIMETER?
(TYPE C OR D)
D
RIGHT YOU ARE
>NOPE.  REMEMBER, A DECIMETER IS LARGER THAN A CENTIMETER.
4NOW, HOW MANY CENTIMETERS ARE IN ONE DECIMETER?
10
OKAY, LET'S MOVE ON.
BNO.  I'M SURE YOU JUST FORGOT THAT THERE ARE 10 CENTIMETERS IN
EACH ONE DECIMETER.
<CHOOSE THE CORRECT ANSWER:  1 DECIMETER = ? CENTIMETERS?
(TYPE 10, 100 OR 1000)
10
"FINE.  I THINK YOU'VE GOT IT.
@NO.  YOU DON'T SEEM TO BE CONCENTRATING:  1 DEC. = 10 CENT.
>TRY THIS TOUGH QUESTION:  REPLACE THE ? WITH YOUR ANSWER.
.IF 1 DEC. = 10 CENT. THEN 2 DEC. = ? CENT.
20
BRILLIANT.
*YOU DON'T SEEM TO BE GETTING THE IDEA.
@IF EACH 1 DECIMETER = 10 CENTIMETERS THEN 2 DEC. = 20 CENT.,
3 DEC. = 30 CENT., ETC.
DBASED ON THE FACTS THAT 1 DEC. = 10 CENT. AND 2 DEC. = 20 CENT.,
COMPLETE THIS SENTENCE:
JIN A GIVEN NUMBER OF DECIMETERS THERE ARE ? TIMES AS MANY CENTIMETERS?
(IS IT 10, 100, OR 1000?)
10

FINE.
"NO THERE ARE 10 TIMES AS MANY.
"CHOOSE THE CORRECT OPERATION:
JTO CHANGE FROM DECIMETERS TO CENTIMETERS WE (ADD, SUBTRACT, MULTIPLY,
0OR DIVIDE?) THE NUMBER OF DECIMETERS BY 10.
(TYPE A, S, M, OR D.)
M
THAT'S CORRECT.
NO, WE MULTIPLY BY 10.
FWE NOW HAVE A RULE FOR CONVERTING FROM DECIMETERS TO CENTIMETERS:
BTO CHANGE A GIVEN NUMBER OF DECIMETERS TO CENTIMETERS MULTIPLY
$THE NUMBER OF DECIMETERS BY 10.
.EXAMPLE:     15 DEC. = 15 X 10 = 150 CENT.
,PLEASE TRY THIS ONE:  39 DEC. = ? CENT.
390
(YOU'VE GOT THE IDEA.  NOW TRY THIS.
4NO, YOU SHOULD HAVE MULTIPLIED BY 10 TO GET 390.
$24.5 DECIMETERS = ? CENTIMETERS?
245
*OKAY, LET'S MOVE ONTO SOMETHING ELSE.
NOT QUITE.
>REMEMBER, WHEN MULTIPLYING A DECIMAL BY 10 YOU SIMPLY MOVE
.THE DECIMAL POINT ONE PLACE TO THE RIGHT.
$        EXAMPLE:  5.6 X 10 = 56
&                 1.36 X 10 = 13.6
WHAT IS 78.35 X 10?

783.5
*OKAY, LET'S MOVE ONTO SOMETHING ELSE.
BNO.  MOVING THE DECIMAL ONE PLACE SHOULD HAVE GIVEN YOU 783.5.
BOKAY.  WE SAW THAT TO CHANGE FROM DECIMETERS TO CENTIMETERS WE
6MULTIPLIED BY 10. (EXAMPLE:  11 DEC. = 110 CENT.)
BSINCE 10 CENT. = 1 DEC., WHAT OPERATION DO YOU THINK WE WOULD
2HAVE TO USE TO SOLVE THIS:  70 CENT. = ? DEC.?
D(TYPE A:ADDITION, S:SUBTRACTION, M:MULTIPLICATION, D :DIVISION)
D
THAT'S RIGHT. GOOD.
.NO, DIVISION IS WHAT WE WERE LOOKING FOR.
DTO CHANGE A GIVEN NUMBER OF CENTIMETERS TO DECIMETERS WE DIVIDE
BY 10.  FOR EXAMPLE:
2                    10 CENT. = 10/10 = 1 DEC.
2                    30 CENT. = 30/10 = 3 DEC.
2                  120 CENT. = 120/10 = 12 DEC.
&WE NOW HAVE A SECOND METRIC RULE:
:TO CHANGE A GIVEN NUMBER OF CENTIMETERS TO DECIMETERS,
,DIVIDE THE NUMBER OF CENTIMETERS BY 10.
*EXAMPLE:  140 CENT. = 140/10 = 14 DEC.
.NOW YOU TRY THIS ONE:  260 CENT. = ? DEC.
26
*RIGHT.  YOU SEEM TO CATCH ON QUICKLY.
BNO.  260/10 SHOULD HAVE GIVEN YOU 26 DECIMETERS FOR AN ANSWER.
&NOW LET'S TAKE A LOOK AT ONE MORE.
DWHAT IS THE CORRECT VALUE TO REPLACE THE ?.  145 CENT. = ? DEC.
14.5
VERY GOOD.
8NO.  YOU PROBABLY GOT CONFUSED IN DIVIDING 145 BY 10
@WHEN DIVIDING A NUMBER BY 10, SIMPLY MOVE THE DECIMAL POINT
@ONE PLACE TO THE LEFT.  IN THE PROBLEM 195/10 THE DECIMAL IS
BACTUALLY AFTER THE 5 ALTHOUGH IT IS NOT PRINTED.  (195.)  SO,
>TO DIVIDE BY 10, WE MOVE THE DECIMAL TO THE LEFT ONE PLACE
 AND OUR ANSWER BECOMES 19.5.
WHAT WOULD 265/10 BE?
26.5
(OKAY.  NOW I THINK YOU GET THE IDEA.
>NO, THE ANSWER IS 26.5.  REMEMBER THE DECIMAL IS MOVED ONE
PLACE TO THE LEFT.
NOW A QUICK REVIEW:
FTO CHANGE DECIMETERS TO CENTIMETERS WE (MULTIPLY, DIVIDE?) BY 10.
(TYPE M OR D)
M

SWELL.
 @NOPE.  YOU GOT THEM CONFUSED.  TO CHANGE FROM DECIMETERS TO
JCENTIMETERS WE MULTIPLY BY 10, BECAUSE THERE WILL BE MORE CENTIMETERS.
 $OKAY.  ONE MORE POINT TO REVIEW.
FTO CHANGE CENTIMETERS TO DECIMETERS WE (MULTIPLY, DIVIDE?) BY 10.
(TYPE M OR D)
D
JYOU'VE DONE GREAT.  YOU ARE NOW READY TO TAKE THE QUIZ ON THESE IDEAS.
METR11M
>YOU GOT CONFUSED.  TO GO FROM CENTIMETERS TO DECIMETERS WE
.DIVIDE BY 10.  THERE ARE FEWER DECIMETERS.
8I THINK YOU ARE READY NOW FOR A QUIZ ON THESE IDEAS.
METR11:DO YOU WISH TO TRY THE QUIZ AGAIN AFTER A LITTLE HELP?
 (TYPE Y FOR YES OR N FOR NO)
Y
 GOOD.  HERE'S A LITTLE HELP.
"N
:OKAY, PLEASE SEE YOUR TEACHER FOR FURTHER INSTRUCTION.
THAT'S ALL FOR NOW.
"NOW LET'S TRY TO CONCENTRATE!
DWHEN CHANGING FROM DECIMETERS TO CENTIMETERS MULTIPLY THE NUMBER
DOF DECIMETERS BY 10.  MAKE SURE YOU ARE GOING FROM DECIMETERS TO
DCENTIMETERS AND NOT THE OTHER WAY.  IF THE NUMBER OF DECIMETERS
@IS A DECIMAL MOVE THE DECIMAL POINT ONE PLACE TO THE RIGHT!
HERE ARE SOME EXAMPLES:

D      15 DEC.= ? CENT.    ANSWER: 15 DEC. = 15 X 10 = 150 CENT.
F     123 DEC. = ? CENT.   ANSWER: 123 DEC. = 123 X 10 = 1230 CENT.
H    15.7 DEC. = ? CENT.   ANSWER: 15.7 DEC. = 15.7 X 10 = 157 CENT.
 
$ARE YOU READY FOR THE QUIZ NOW?
(TYPE Y OR N)
Y
OKAY, HERE GOES!
METR11N
,OKAY.  PLEASE SEE YOUR TEACHER FOR HELP.
THAT'S ALL FOR NOW!
4DO YOU WANT TO TRY THE QUIZ AGAIN AFTER A LITTLE

HELP?
"(TYPE Y FOR YES AND N FOR NO)
Y
&OKAY.  HERE'S A LITTLE HELP FIRST.
$,OKAY.  PLEASE SEE YOUR TEACHER FOR HELP.
THAT'S ALL FOR NOW.
$OKAY, LET'S TRY TO CONCENTRATE!
BWHEN CHANGING FROM CENTIMETERS TO DECIMETERS WE DIVIDE BY 10.
HMAKE SURE, THOUGH, THAT YOU ARE GOING FROM CENTIMETERS TO DECIMETERS
DAND NOT THE OTHER WAY AROUND.  IF THE NUMBER OF CENTIMETERS IS A
@DECIMAL OR A NUMBER THAT DOES NOT END IN 0, SIMPLY MOVE THE
*DECIMAL POINT ONE PLACE TO THE LEFT.!
HERE ARE SOME EXAMPLES:

@   60 CENT. = ? DEC.      ANSWER:  60 CENT. = 60/10 = 6 DEC.
B  130 CENT. = ? DEC.      ANSWER: 130 CENT. = 130/10 = 13 DEC.
D  296 CENT. = ? DEC.      ANSWER: 296 CENT. = 296/10 = 29.6 DEC.

$ARE YOU READY FOR THE QUIZ NOW?
(TYPE Y OR N)
Y
OKAY, HERE GOES!
METR11N
,OKAY.  PLEASE SEE YOUR TEACHER FOR HELP.
THAT'S ALL FOR NOW.
S NOT END IN 0, SIMPLY MOVE THE
*DECIMAL POINT ONE PLACE TO THE LEFT.!
HERE ARE SOME EXAMPLES:

@   60 CENT. = ? DEC.      ANSWER:  60 CENT. = 60/10 = 6 DEC.
B  130 CENT. = ? DEC.      ANSWER: 130 CENT. = 130/10 = 13 DEC.
D  296 CENT. = ? DEC.      ANSWER: 296 CENT.
