Question

Nora has a flower arrangement with 7 pink flowers, 9 purple

flowers, and 5 white flowers. Which sentence is not true?

The ratio of total flowers to pink flowers is 21: 7

The ratio of white
flowers to purple flowers is 5:9.

The ratio of purple flowers to total flowers is 16 to 21.

Answer 1

The ratio of purple flowers to total flowers is 16 to 21 is NOT TRUE because your total is already 21 so it would make no sense for 16 to be in the ratio
