Solution: Add them together twice, and the formula is 8/ 15 safflower+1/2 yellow flower +8/ 15 white flower =40+44=84 1;

If we take 1/2 respectively, that is, 1/2 red flowers+1/2 yellow flowers+1/2 white flowers =80.

1 formula -2 The formula has three forms: 1/30 safflower+1/30 white flower =4- > safflower+white flower = 120 flower.

Then yellow flower = 160- 120=40.

According to the meaning of the question:

1/3 safflower+1/4 yellow flower+1/5 white flower = 44-4 formula

1/5 safflower+1/4 yellow flower+1/3 white flower = 40-5 formula

Formula -5 is 2/ 15 safflower -2/ 15 white flower = 4- safflower-white flower =30 6 formula.

Equations 3 and 6 are: 75 red flowers and 45 white flowers.
