Common Denominator of 20 and 25

To find the common denominator of 20 and 25, we need to determine the smallest number that both 20 and 25 can divide evenly into.

The common denominator of two numbers is the smallest multiple that both numbers share. In this case, we are looking for the smallest number that both 20 and 25 can divide into without leaving a remainder.

To find the common denominator, we can list the multiples of each number and look for the first multiple that they have in common:

- Multiples of 20: 20, 40, 60, 80, 100, ... - Multiples of 25: 25, 50, 75, 100, ...

From the lists above, we can see that the first multiple that both 20 and 25 have in common is 100. Therefore, the common denominator of 20 and 25 is 100.

How to Find the Common Denominator

To find the common denominator between two numbers, you can follow these steps:

1. List the multiples of each number. 2. Identify the first multiple that both numbers have in common. 3. That common multiple is the common denominator.

In this case, we listed the multiples of 20 and 25 and found that the first multiple they have in common is 100.
