Example 1

Let's subtract 15% from 200.


200 - (15/100 * 200) = 200 - 30 = 170

The difference after subtracting 15% from 200 is 170.

Example 2

Subtract 25% from 800.


800 - (25/100 * 800) = 800 - 200 = 600

The difference after subtracting 25% from 800 is 600.

Example 3

Subtract 10% from 1500.


1500 - (10/100 * 1500) = 1500 - 150 = 1350

The difference after subtracting 10% from 1500 is 1350.

Example 4

Subtract 5% from 50.

Calculation: 50 - (5/100 * 50) = 50 - 2.5 = 47.5

The difference after subtracting 5% from 50 is 47.5.
