If 40% of a class of 25 students pass a test, how many passed?

Explanation:
40% means four-tenths of the total. With 25 students, four-tenths of 25 is (4/10) × 25 = 100/10 = 10. You can also view 40% as 2/5, and 2/5 of 25 is 10. Quick check: 10 passed out of 25 is 10/25 = 0.4, which is 40%. Ten students passed.
