Student-Friendly Standard Goal
I can use equivalent forms of rational numbers to solve percent problems.
- Fractions, decimals, and percents can name the same amount in different ways.
- Benchmark percents are friendly values like 10%, 25%, 50%, and 75%.
- To find a percent of a number, connect the percent to a fraction or decimal you understand.
