Explanation:
When changing a decimal to a fraction, think of the decimal "out of 1." In mathematical terms, "out of" generally suggests division.
For example on this question, think of 0.2 as 0.2 out of 1, which would be shown as
0.21
To more easily simplify this, multiply both the top and bottom by 10:
0.211010
You are able to do this because 1010 is equal to 1 and multiplying by a number and 1 results in the same number.
Then you get 210. Both 2 and 10 are divisible by 2:
22=1 and 102=5
So the final answer is 15

Explanation:
The way it is read essentially gives away the answer. 0.2 is rad as "Two tenths", which means the fraction is out of 10. The numerator is 2.
This can be interpreted as
210, or in simplest form, 15
Another method is to realize that we can express any number as a fraction if we put it over 1
0.21
Since decimals arent
