Step-by-step explanation:
5 : 6 = Number of boys to girls
(We have to ×2 to get from 5 to 10 so we must ×2 from 6 to 12)
10 : ? = Number of Boys to girls
10 : 12 = Number of Boys to girls
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.
