Can someone help me I can't remember how to do ratios

Mathematics

3 casseroles feeds 15 people

The ratio is 3:15

If you divide each of those by 3, youll find that 1 casserole feeds 5 people

1 : 5 is the ratio.

Divide 30 by 5 = 6

6 casseroles feeds 30 people.

6 : 30

35 divided by 5 = 7

7 casseroles feed 35 people

7 : 35
