Percentage of a number
A percentage is just a fraction of 100. To find "15% of 240," convert 15%
into a decimal (15 / 100 = 0.15) and multiply: 240 * 0.15. That's the
whole trick - every "what's X% of Y" question is one multiplication once the
percent is written as a decimal.
The starter expression shows the shape (10% of 50) - it isn't this lesson's
answer.
Your task: what is 15% of 240?
You'll practice:
- Converting a percentage to a decimal before multiplying
- Writing a two-step calculation as a single expression
