Enter any ratio (X/Y) into the Inverse Ratio Calculator. The calculator will evaluate and display the Inverse Ratio.

## Inverse Ratio Formula

The following formula is used to calculate the Inverse Ratio.

**IR = 1 / R**

- Where IR is the Inverse Ratio (Y/X)
- R is the any ratio (X/Y)

## How to Calculate Inverse Ratio?

The following example problems outline how to calculate Inverse Ratio.

Example Problem #1:

- First, determine the any ratio (X/Y).
- The any ratio (X/Y) is given as: 4/5.

- Finally, calculate the Inverse Ratio using the equation above:

IR = 1 / R

The values given above are inserted into the equation below and the solution is calculated:

IR = 1 / (4/5) = 5/4

Example Problem #2:** **

For this problem, the variables required are provided below:

any ratio (X/Y) = 6/10

Test your knowledge using the equation and check your answer with the calculator above.

IR = 1 / R** = ?**
