Answer:

There were 27 apples.

Explanation:

Set a ratio of bananas to apples like this:

bananas/apples = 2/3

Now you have 18 bananas. The number of apples is unknown, so use "a" for the number of apples.

bananas/apples = 18/a

The two ratios above are equal, so set them equal. That creates a proportion.

2/3 = 18/a

Now we solve for a by cross multiplying.

2a = 3 * 18

2a = 54

a = 27

Answer: There were 27 apples.
