About this math lesson
Ratios compare two amounts, and percents compare an amount to 100. This free 6th grade math video shows how to write and simplify ratios, what percent means, and how to use both in real situations like recipes and sales.
Key ideas
- A ratio can be written 3 to 2, 3:2 or 3/2
- Percent means per hundred: 25% = 25/100
- To find 10% of a number, divide it by 10
- Equivalent ratios, like 2:3 and 4:6, show the same relationship
Questions parents and teachers ask
What is a ratio in math?
A ratio compares two quantities. If there are 3 red apples and 2 green apples, the ratio of red to green is 3:2.
How do you turn a fraction into a percent?
Make the denominator 100, or divide and multiply by 100. For example, 3/4 = 0.75 = 75%.
What grade learns ratios and percents?
Ratios, rates and percents are major topics in 6th grade math in most US schools.
