Answer:

8

Step-by-step explanation:

So there are 20 balls.

3/5 of them are NOT white.

This means 2/5 of them ARE white.

So knowing this, lets find the number of white balls(x).

To do this, lets multiply the 20 total balls by the 2/5 of them that are white:

20/1*2/5

=

40/5

=

8

So we know that 8 of the balls are white!

Hope this helps! :)
