Answer: 36

12 out of 15 people play in the school band. In the class, 36 do not play.

12:15 is equal to a ration of 36:45.

So, it is the answer. 36 out of 45 people in the class play in the band.

Hope this helps!

Answer:

9 I think

Step-by-step explanation:

I wanted to simplify 12 out of 15 and I did by dividing 3 out of both of them which would now equal 4 out of 5. I know that 4 out of 5 is 80%. so, I did 80 % of 45 which equals 36 which means 36 people were in band. So now you minus 36 from 45 which is 9

9 people did not play in band
