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, 0.45 is the number on the numerator and the base number 1 will be the denominator. Then, 0.45 becomes 0.45/1.
