Question

The ratio of boys to girls in band class was 3 to 5. If there were 24 boys. How many girls were in band class?

Answer 1

Answer:

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

$\frac{3}{5}$ = $\frac{24}{x}$

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer 2

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

$\frac{3}{5} = \frac{24}{x}$

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.
