What are proportions?

Proportions show a relationship between two ratios. Even though the ratios might look different, they are connected in a similar way.

Proportions are used in many everyday situations. Knowing one ratio lets you figure out related values in other ratios — from baking recipes to advanced sciences.

Example:
Cooking shows often share ingredient lists for 2 - 3 servings. If you want to scale a recipe for more people, a proportion calculator can quickly help you find the right amount of each ingredient.

Proportion solving steps:

There’s no fixed formula for solving proportions — it's more about simple steps. For example, if you have two ratios: (a) 2:3 and (b) 7:x

To find x:

1. Write both ratios as fractions.

2. Cross-multiply.

3. Isolate x and solve.

You'll find the missing value easily!
