Question

The ratio of juniors to seniors at a certain high school is 11:10. If there are 110 seniors in the school, how many juniors are there?

A) 90
B 100
C) 120
D) 121

Answer 1

The number of juniors in the high school is 121.

Step-by-step explanation:

To find the number of juniors in the high school, we can use the given ratio of juniors to seniors. The ratio is 11:10, which means that for every 11 juniors, there are 10 seniors. If there are 110 seniors in the school, we can set up the proportion:

11 / 10 = x / 110

To solve for x, we can cross multiply:

11 * 110 = 10 * x

1210 = 10x

Dividing both sides by 10, we find:

x = 121

Therefore, there are 121 juniors in the high school.
