How do I rewrite a problem so that the divisor is a whole number? Move the decimal point enough places to the right to make the divisor a whole number. You must move the decimal point in the dividend the same number of places to the right.
4.7 divided by 13.6 is 47/136
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 =
, but 0.232323... = 
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x = 
d) -2
<em>= -2
when simplified</em>
The number is rational becase it has a repeating decimal
The answer to 8 + 11 is 19
