Ratios and Unit Rates
Learning Objective
I can explain the concept of a ratio and unit rate.
Key Concepts
A ratio is a way to compare two numbers by division, showing the relationship between them rather than their absolute values.
Ratios can be written in fraction form or using the colon symbol ( : ), and a rate is a special type of ratio that compares quantities involving a period of time.
A unit rate simplifies a rate by expressing it with a denominator of 1, making it easier to compare different rates.
