3/8 of 32 would be 12, and 2/8 of 32 would be 8. Because these fractions are different colors, you could add them to get 20, then subtract 32 - 20 to get 12. Therefore, 12 of the cards were green (or 3/8). You could also find the answer by thinking of it in terms of fractions only; 3/8 + 2/8 = 5/8, which means the other 3/8 adds up to 32 cards. As mentioned above, 3/8 of 32 is 12, so again, 12 playing cards were green. Hope this was helpful and understandable for you!
