Simplifying Ratios: A Step-by-Step Guide
Ratios are used to compare quantities of different things. A ratio can be expressed as a fraction, a proportion, or a relationship between two or more numbers. However, not all ratios are simple and easy to understand. That’s where simplifying ratios comes in.
What is Simplifying Ratios?
Simplifying ratios means expressing a ratio in its simplest form, where the numbers in the ratio are reduced to their lowest terms. This makes it easier to understand and work with ratios.
Why Simplify Ratios?
Simplifying ratios is important because it:
- Makes ratios easier to understand and compare
- Helps to avoid confusion when working with ratios
- Allows for easier calculations and problem-solving
- Enables the identification of equivalent ratios
How to Simplify Ratios
Simplifying ratios is a straightforward process that involves dividing both numbers in the ratio by the greatest common divisor (GCD) of the two numbers. Here are the steps:
- Find the greatest common divisor (GCD): The GCD is the largest number that divides both numbers in the ratio without leaving a remainder.
- Divide both numbers by the GCD: Divide the numerator (top number) and the denominator (bottom number) by the GCD.
- Simplify the ratio: The resulting ratio is the simplified form of the original ratio.
Examples of Simplifying Ratios
Let’s consider some examples to illustrate the process of simplifying ratios.
Example 1: Simplify the ratio 6:8
- Find the GCD: 2
- Divide both numbers by the GCD: 6 ÷ 2 = 3, 8 ÷ 2 = 4
- Simplified ratio: 3:4
Example 2: Simplify the ratio 12:16
- Find the GCD: 4
- Divide both numbers by the GCD: 12 ÷ 4 = 3, 16 ÷ 4 = 4
- Simplified ratio: 3:4
Example 3: Simplify the ratio 20:25
- Find the GCD: 5
- Divide both numbers by the GCD: 20 ÷ 5 = 4, 25 ÷ 5 = 5
- Simplified ratio: 4:5
