How to calculate Rule of 3 in Excel

Rule of three is a method used to solve proportion problems between quantities. In Excel, it is possible to perform this calculation quickly and efficiently. In this article, we will show you how to calculate rule of three in Excel step by step.

Step 1: Organize the data

Before starting the calculation, it is important to organize the data properly. To do this, create a table with the known quantities and the unknown you want to find. For example:


Known Greats
Unknowns



Greatness 1 Unknown 1
Greatness 2 Unknown 2

Step 2: Enter the values ​​

Now enter the known values ​​in the corresponding cells of the table. For example:


Known Greats
Unknowns



Greatness 1 Value 1
Greatness 2 Value 2

Step 3: Perform the calculation

In Excel, it is possible to calculate the Rule of Three Using the Formula = Unknown value * Incognita_connhecide / known value . For example:

= B2 * C1 / B1

This formula will multiply the value known by the known unknown and divide by the known value. The result will be the unknown desired.

Practical Example

Let’s suppose that you want to calculate the amount of liters of water needed to fill a tank according to the tank capacity and the amount of hours available to fill it. The tank capacity is 500 liters and you have 2 hours available. Using the rule of three, we can calculate the amount of liters per hour:

= 500 * 1/2

The result will be 250 liters per hour.

Conclusion

Excel is a powerful tool for making calculations, including the three rule. With the steps presented in this article, you can calculate the rule of three quickly and efficiently. Remember to organize the data correctly and use the right formula. Try using Excel to solve other mathematical problems and enjoy all the resources that this tool offers.
