The ratio of tomatos to potatoes is 3: 2 if there are 20 potatoes how many tomatoes are there?

There are a couple ways to do this, but I'll go with the easier among them.

We know that the 2 potatoes increased to 20.

We want to find out what number the two multiplied by to get 20. This calls for division.

20/2 = 10

Since ratios must be multiplied by the same number, we have to multiply the 3.

3 • 10 = 30

There are 30 tomatoes.

Ihave, but this question is gonna probably get deleted.
