Explanation
Converting a decimal to a fraction is a task for students that can be done easily. You can follow the steps mentioned below to find the answer.
Step 1: Firstly, any decimal number should be converted to a fraction for easy calculation. Here, 20.25 is the number on the numerator and the base number 1 will be the denominator. Then, 20.25 becomes 20.25/1.
