If you're still reading, I'll assume you want to know how to get there. Fair enough.
The Simple Method: Multiply
Turn your percentage into a decimal and multiply.
15% = 0.15
15 × 0.15 = 2.25
You can also think of it as a fraction: 15% = 15/100. So 15 × 15/100 = 225/100 = 2.25.
Another Way: Use 10% First
Some people find this easier in their head:
- 10% of 15 = 1.5
- 5% of 15 = 0.75
- 1.5 + 0.75 = 2.25
Works every time.
