Answer: Yellow flowers 3 1/3 And red flowers 7
Explanation:
So you take 3 and put into 1/3. You get 3 1/3 because if you multiply them together you get 21 and there's 21 yellow flowers in total. Then for "R" (red flowers) you would divide 21 by 3 (the reason you divided it by 3 is because there's 3 times the number of red flowers.) you would get 7.
Yellow Flowers: 3 1/3
Red Flowers: 7
