Total number of children in the class = 12 + 18 = 30
There are 12 boys
12 of the 30 students are boys
The fraction of the class that are boys = 12/30
ASIDE: When it comes to entering fractions in a Numeric Entry question on the GRE, you are NOT required to express the fraction in simplest. All equivalent fractions are considered correct.
So, an answer of 12/30 is considered correct.
An answer of 6/15 is ALSO considered correct.
And an answer of 2/5 is considered correct.
And an answer of 20/500 is considered correct.
