1/2 of 40= 20

40/5=8

20+8=28

28 of your CDs will not work properly.

I hope this helps!

So the 1/2 of the CDs that are scratched and the 1/5 that will not play properly would be counted towards the "How many will not work play properly."

So, you just want to find 1/2 of the CD count, and 1/5 of the CD count, and add them together.

1/2 of the CD count:

Just multiply 1/2 by 40. 1/2 * 40 = 40/2 = 20

So 1/2 of the CD count = 20.

Then 1/5:

1/5 * 40

40/5

8

So 8 = 1/5 of 40.

Since the total would be those two added together, you would add 8 and 20 together.

8 + 20 = 28
