Students will be able to:
understand that equivalent ratios can be used to model percent problems.
analyze percents of numbers in a real-world context.
Equivalent ratios can be used to solve percent problems by writing the percent as a rate per 100.
A percent is one way to represent the relationship between two quantities, generally that of a part to the whole.
[Bar model: 100% represents 15, while 60% represents x.]
60/100 = x/15
[Inferred by solving the model: x = 9.]
