In a math word problem, if 2/5 of the class are girls and there are 25 students, how many girls are there?

Explanation:
Applying a fraction to a total to find a part shows why 2/5 of 25 equals 10. Multiply 25 by 2/5: 25 × (2/5) = (25/5) × 2 = 5 × 2 = 10. Another way is to split 25 into five equal groups of 5; two groups give 2×5 = 10. The numbers 15, 20, and 5 would come from 3/5, 4/5, and 1/5 of 25 respectively, so with 2/5, the count is 10.
