How to approach percent problems
Percent means “per hundred.” To find a percent of a quantity, convert the percent to a decimal or fraction and multiply by the whole.
Percent equations connect part, whole, and rate: part = rate × whole. Labeling which quantity plays each role prevents the common mistake of dividing in the wrong order.
Learning objectives
- Find a percent of a number
