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)

To calculate an inverse ratio, divide 1 by the original ratio.

## How to Calculate Inverse Ratio?

The following example problems outline how to calculate Inverse Ratio.

Example Problem #1:

1. First, determine the any ratio (X/Y).
• The any ratio (X/Y) is given as: 4/5.
2. 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 = ?
