## What are proportions?

Proportion is a statement which tells us that two ratios are equal. The symbol of proportion is **‘::’ **and **‘=’.**

For example, two ratios are in proportion if they are equal to each other.

## How to solve proportions?

Solving proportions is easier than you think. Let’s solve a proportion with an example.

*Example:*

If ratio of pizzas to burgers is *3/5* in a party, how many of burgers will be there if there are total of *15* burgers.

**Solution:**

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

*3/5 = x/15*

**Step 2: **Apply cross multiplication to the above equation.

*5x = 3 × 15*

*x = 45/5*

*x = 9*

So, there will be *9 *pizzas with *15* burgers.
