Using multipliers to increase a number by a percentage.
To increase a number by a percentage:
1.Change the percentage you're going to increase the number by into a decimal
2. Put a 1 before the decimal to make it 1 point something (look at example below)
3. Multiply the number that you have been told to increase by the decimal with 1 point...
EXAMPLE:
Increase 240 by 25%:
1. 25 % = 0.25
2.0.25 becomes 1.25
3. 1.25 * 240 = 300
