Question

At a school 141 students play at least one sport. This is 30% of students at that school. How many students are at the school

Answer 1

There are 470 students at the school.

Explanation:

141 / x = 3 / 10 since 3/10 is equal to 30% you're looking for a denominator that corresponds equally to 141 and when simplified, 141 / x equals 3 / 10.

Use algebra to solve: 141 * 10 = 3x → 1410 = 3x → 470 = x.
