A result like 67.5 is realistic, manageable, and worth understanding properly because it mirrors everyday business and personal finance decisions.

Mental Maths Shortcut
The fastest way to estimate 15% is to split it into 10% + 5%:
- 10% of 450 = 45
- 5% of 450 = 22.5
- 45 + 22.5 = 67.5
This is a strong example of a semi-round result. The steps are very manageable, but the final answer still reminds you to expect decimals or half-values when percentages are applied to ordinary totals. If you want a nearby base where 15% produces a different kind of decimal, 15% of 320 is another useful contrast.
