Question

There are 15 female students in Ms. Stell's World History Class. The ratio of females to males is 5:4. How many males are in her class?​

Answer 1

Answer:

There are 12 boys in Ms. Stell's World History Class.

Step-by-step explanation:

The ratio we are given is 5:4.

*5 is the simplified version of 15

*4 is the simplified version of x (total number of boys)

The first thing we need to do is find the number that gives us the total number of girls (15)

5*3 = 15.

Now we do that for the 4.

$\frac{5*3}{4*3}$ = $\frac{15}{12}$

The answer should be 15:12

Best of Luck!

Answer 2

Answer:

12

Step-by-step explanation:

Since 15 is 3 times the ratio you multiply 4 by 3
