By the end of this discussion, you will have a clear understanding of how to simplify ratios and express them in their simplest form.
What are Ratios?
A ratio is a way of comparing two or more quantities by division. It is often expressed as a fraction, with the first quantity as the numerator and the second quantity as the denominator. For example, the ratio of can be written as .
Simplifying Ratios: A Step-by-Step Guide
To simplify a ratio, we need to find the greatest common divisor (GCD) of the two quantities. The GCD is the largest number that divides both quantities without leaving a remainder. Once we have found the GCD, we can divide both quantities by the GCD to simplify the ratio.
Example 1: Simplifying the Ratio
To simplify the ratio , we need to find the GCD of and . The factors of are and , while the factors of are and . The greatest common factor of and is . Since the GCD is , we cannot simplify the ratio further.
# Example 1: Simplifying the Ratio 3:2
## Step 1: Find the GCD of 3 and 2
The factors of 3 are 1 and 3, while the factors of 2 are 1 and 2.
The greatest common factor of 3 and 2 is 1.
## Step 2: Simplify the Ratio
Since the GCD is 1, we cannot simplify the ratio further.
The simplified ratio is 3:2.
Example 2: Simplifying the Ratio
To simplify the ratio , we need to find the GCD of and . The factors of are , while the factors of are . The greatest common factor of and is . We can divide both quantities by to simplify the ratio.
# Example 2: Simplifying the Ratio 40:60
## Step 1: Find the GCD of 40 and 60
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40, while the factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
The greatest common factor of 40 and 60 is 20.
## Step 2: Simplify the Ratio
We can divide both quantities by 20 to simplify the ratio.
The simplified ratio is 2:3.
