A class has 80 students, and 12 of them walk to school. What percent of the students in the class walk to school?

Question

Accepted Answer

A. 15%. The part is 12 and the whole is 80. Percent means per hundred, so compute the fraction and scale it: 12/80 = 0.15 = 15%.

Answer

B. 6.67% — 6.67% is 80/12 — the whole divided by the part, upside down. The part goes on top: 12/80.

Answer

C. 68% — 68% is (80 − 12)/80, the percent who do NOT walk. The question asks about those who do.

Answer

D. 1.5% — 1.5% is 12/80 written as 0.015 instead of 0.15. 12/80 is 0.15, and 0.15 is 15 per hundred.
