If I have 20 apples and I give away 7%, how many apples do I have left?

0.93 * 20 = 18.6

There's probably a typo in your problem since it's unlikely you'll have a fraction of an apple left.

To find out how many apples you have left after giving away 7%, you can follow these steps:

Step 1: Calculate the number of apples you are giving away.
To find 7% of 20 apples, you need to multiply 20 by 7% (or 0.07).

Number of apples given away = 20 * 0.07 = 1.4 apples

Step 2: Subtract the number of apples given away from the total number of apples.
To determine the remaining number of apples, subtract the result from step 1 from the initial total of 20 apples.

Remaining number of apples = 20 - 1.4 = 18.6 apples

Therefore, after giving away 7% of your apples, you will have approximately 18.6 apples left.
