Ratio is a way of comparing or relating one thing with other. Finding the ratio between two numbers come handy in many aspects of data analysis. We can use the GCD function in Excel to find the ratio between two numbers. In this tutorial, we will learn how to find the ration from two numbers.
Figure 1. Example of How to Find Ratio From Two Numbers
Syntax
=num1/GCD(num1,num2)&":"&num2/GCD(num1,num2)
How this Formula Works
This formula is based on the GCD function. The two numbers are represented as num1 and num2. Here, we need to calculate the GCD of the two numbers. First, we divide the first number with the GCD. We repeat the same thing with the second number. Lastly, we join them with the concatenate operator (“&”). We use the colon (“:”) to separate the result of the two GCD results.
Setting up Data
The following example contains a spouse age database. Column A and B contains the ages for both the spouses.
Figure 2. The Data Set
To show the ratio between the ages in column D:
- We need to go to cell C2.
- Apply the formula
=A2/(GCD(A2,B2))&":"&B2/GCD(A2,B2)to C2. - Press Enter.
Figure 3. Applying the Formula
- Drag the formula using the fill handle in the bottom right from cells C2 to C6.
This will show the ratios in column C.
