## What are proportions?

Proportion is a mathematical equation that defines that the two given ratios are equivalent to each other. The symbols used to represent proportion are “::” and “=” respectively.

For instance, two ratios in proportion if they are equal:

4/8 = 7/14.

## How to solve a proportion?

There are different ways to solve the proportion. Let us solve a random proportion with some examples.

Example No.1:

In a school cafeteria, the ratio of sandwiches to salads is 4/7. If there are a total of 28 salads, how many sandwiches are there?

Solution:

Step 1: Construct a proportion using the given values and x.

4/7 = x/28

Step 2: Apply cross multiplication to the above equation.

7x = 4 × 28

x = (4 × 28)/7

x = 112/7

x = 16.

So, there will be 16 sandwiches if there are a total of 28 salads.

To verify the results with our proportion solver, we have entered the same values in the required fields, and here are the results:

Example No.2:

If the ratio of apples to oranges in a fruit basket is 4:7, and there are a total of 84 oranges, how many apples are there?

Solution:

Step 1: Construct a proportion using the given values and x.

4/7 = x/84

Step 2: Apply cross multiplication to the above equation.

7x = 4 × 84

x = (4 × 84) / 7

x = 336 / 7

x = 48.

So, there will be 48 apples when there are 84 oranges in the fruit basket.
