## Ratio to Percentage Conversion

Ratio to percentage conversion helps us in obtaining accuracy in mixtures of elements, or while calculating the percentage score in a test. At times you are given parts of a quantity in the form of ratios. They can also be represented in the form of percentages. Let us understand this with the help of examples.

Go through the following procedure to understand how to convert the ratio to percentage:

**Step 1:** First write the ratio a:b in the form of fraction a/b.

**Step 2:** Multiply the fraction a/b by 100 to convert in terms of percentage.

**Step 3:** Finally, add the percentage symbol (%) to the resultant value.

For example, to convert the ratio 5: 4, follow the below steps:

Step 1: The ratio 5:4 is written as 5/4.

Step 2: Multiply 5/4 by 100. (i.e) (5/4)×100 = 125.

Step 3: Adding the percentage symbol (%) to the resultant value, we get 125%.

### Ratio to Percent Examples

**Example 1:**

Convert the ratio 2:1 into percentage.

**Solution:**

Given ratio: 2:1

Step 1: The ratio 2:1 is written as 2/1.

Step 2: Multiplying 2/1 by 100 we get 200. (i.e) (2/1)×100 = 200.

Step 3: Adding the percentage symbol to the resultant value, we get the answer as 200%.

Therefore, 2:1 = 200%.

**Example 2:**

Varun received his monthly salary. The ratio of his expenditure to savings is 7:3. What percentage of his salary, did he spend and what percentage was saved by him?

**Solution:**

Since the part of saving and expenditure are 3 and 7, the salary can be taken as 3 + 7 = 10 parts. This implies, 7/10 part of the salary is spent whereas 3/10 parts are saved.

Converting ratio to percentage we get,

Percentage of expenditure = 7/10 x 100% = 70%

Similarly, percentage of savings = 3/10 x 100% = 30%

**Example 3:**

The angles of a triangle are in the ratio 1:1:2. Find the value of each angle. What will be the percentage of each angle?

**Solution: **

Since the angles are in ratio 1:1:2, there are 1 + 1 + 2 = 4 parts. The sum of angles in a triangle is 180 degrees.

Thus, the measure of the first angle = 1/4 x 180 = 45 degrees

Measure of the second angle = 1/4 x 180 = 45 degrees

Measure of the third angle = 2/4 x 180 = 90 degrees

Similarly, converting ratio to percentage we have,

First angle = 1/4 x 100% = 25%

Second angle = 1/4 x 100% = 25%

Third angle = 2/4 x 100% = 50%
