How do you turn a decimal into a fraction?

Answers

ok so remember
0.1=tenth=1/10
0.01=hundreth=1/100
0.001=thousantht=1/1000
and so on
you just count how many decimal places it is

example

0.3=3/10

0.04=4/1000

0.0343=343/10000
In order to turn a fraction into a decimal, you simply have to complete the fraction by dividing the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction).

For example, say we have the fraction (1)/(5). All we have to do to convert it into a decimal is divide 1 by 5.

1 / 5 = 0.2

So, the fraction (1)/(5) written as a decimal would be 0.2.
Hope that helped! =)
