What Are Ratio and Proportion?
A ratio compares two quantities of the same kind. It is commonly written using a colon, such as 2:3. A proportion states that two ratios are equal.
- Ratio: Comparison of two quantities.
- Equivalent ratios: Ratios with the same value.
- Proportion: Equality between two ratios.
- Direct proportion: Two quantities change in the same direction at a constant rate.
- Inverse proportion: One quantity increases as the other decreases, under the relevant conditions.
Example of Ratio and Proportion
If two quantities are in the ratio 2:3, their total number of equal parts is 2 + 3 = 5.
If the total is 25, one part is 25 ÷ 5 = 5. Therefore, the quantities are 2 × 5 = 10 and 3 × 5 = 15.
