There are 16 girls and 20 boys in the school band. What is the ratio of girls to boys? Express the ratio as a fraction in simplest form.

4:5

Step-by-step explanation:

Since there are 16 girls and 20 boys, the ratio would be 16:20. Since you are wanting it in simplest form, you will divide until you can't divide any more. But what you do to the one side, you have to do to the other.

16/2=8

20/2=10

8/2=4

10/2=5

You can't divide anymore because 5 is odd. So the answer is 4:5

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

i think the answer is 90 hope this
