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) 110 juniors

b) 100 juniors

c) 121 juniors

d) 105 juniors

Answer 1

The number of juniors is found by calculating the ratio multiplied by the number of seniors, which gives us 121 juniors in total.

Step-by-step explanation:

The question asks us to determine the number of juniors at a high school when the ratio of juniors to seniors is given as 11:10, and there are a total of 110 seniors. To solve this, we can set up a proportion using the ratio 11:10 to find the corresponding number of juniors.

Let the number of juniors be represented by 'J'. The ratio can be written as:

J / seniors = 11/10

Substituting the given number of seniors (110), we have:

J / 110 = 11/10

Multiplying both sides by 110 gives us:

J = (11/10) * 110 = 121

Therefore, there are 121 juniors at the high school, which corresponds to option (c).
