well i think you multiply 4 by 125 but i don't know and its not one of my options i have

Here's your original problem:

125 pounds decreased by 4%

You need to convert the percent to a decimal. Move the decimal point two places to the left. 4% = 0.04

Multiply 125 by 0.04

Subtract your answer from 125.

If you need to multiply 4 by 125, you can calculate it by using the multiplication operation.

4 multiplied by 125 equals 500.

However, if multiplying 4 by 125 is not one of the options you have, there may be another way to reach the answer. Could you please provide the available options?
