There are nine men for every 10 women In a particular High school. There are 2622 students at the school. How many women are there?

Answer 1

It helps to write out the words first, so you don't get confused later on:

men/women = 9/10

So, for every 19 students, 9 are men and 10 are women.

Now, take the total student body of 2622 and divide it by 19 to get a factor of 138.

2622 = 138

19

Multiply by the factor:

9x138 = 1242

10x138 1380

The answer asks for the number of women, so let's go back to the top. Oh yeah, women is the denominator, so our answer is 1380.
