Proportion Calculator: Finding the proportion calculator is no more difficult as we have provided you with a best proportion calculator tool that finds the value of the unknown value in the proportion equation. Just by giving some inputs, we will get the output easily without any hard work. In further sections, we have also provided detailed steps and some solved examples.

What is Proportion?

In mathematics, proportions are the one that tells us two ratios are equal. Proportions are mainly used in unit conversions and also while changing numbers in some problems. Proportion is denoted by the symbols, "::" or "=". If a/b and c/d are two ratios then the proportion is expressed as, a/b = c/d (or) a:b :: c:d.

For finding the value of b when you know the value a,c,d then b = (c / d) * a.

How to Calculate Proportion Manually?

To calculate the proportions manually we need to follow some steps to calculate the proportion easily.

Step 1: Firstly, write down the given ratio that was given in the problem in the form of a/b = c/d.

Step 2: Then, if you are going to find the value of a, then the formula you need to use is a= (c / d) * b.

Step 3: If you are going to find the value of b, then the formula you need to use is b= (d/c) * a.

Step 4: Finally after some simplication, we will get the unknown value.

Example:

Question: If the ratio of sandwiches and pizzas is 5/4 then how many sandwiches we will have if we have 10 pizzas?

Solution:

Given, the proportion is 5 / 4 = x / 10.

Now apply the formula, 

a= (c / d) * b.

x= (5/4) * 10

x = 50/4 

x = 12.5

Therefore, the value of sandwiches when we have 10 pizzas is 12.5.
