A flower garden has 12 sunflowers for every 45 irises. Write another ratio with the same constant of proportionality. Explain how you found this ratio.

The ratio of sunflowers to irises is 12:45

This means every 12 sunflowers you find there will be 45 irises.

To find an equivalent ratio simply divide or multiply the ratio like below.

12:45 multiply 2 = 24:90

This says very 24 sunflowers there will be 90 irises which is the same ratio we began with.
