Find the Whole Number Calculator

Formula

To find the original number, you divide the given number by the given percentage. In order to find 1%. Then multiply by 100. 

Given number / Given percentage * 100 = (x)

Examples

1) 40% of people from an office have caught the flu. This accounts for 50 people. How many people work in the office?

50 / 40 * 100 = 125 people

2) A coat is reduced in a sale by 25%. This equates to a saving of £45. How much did the coat cost originally?

45 / 25 * 100 = £180

3) 57 flights go to Paris each month. This is 6% of all flights leaving Gatwick airport. How many flights leave Gatwick airport each month?

57 / 6 * 100 = 950 Flights

Practical Applications of the Calculator

This calculator has a wide range of practical uses. For businesses, it can be used to determine the full price of a product based on a discounted part and percentage.

In education, students often use it to solve reverse-percentage problems in subjects like algebra or statistics. It can also be helpful for personal finance, such as when calculating original amounts based on savings or interest percentages.

Its versatility and ease of use make it a valuable tool for anyone who needs quick and accurate results.

How the Calculator Works

The calculator uses a simple formula to reverse-engineer the whole number from a given part and percentage. Specifically, the formula divides the part by the percentage expressed as a decimal.

For example, if you know that 50 is 25% of a number, the calculator will determine that the whole number is 200.

The user only needs to input the part of the number and the percentage it represents, and the calculator instantly processes the inputs to reveal the whole number
