What is 21.5 as a Fraction?
Answer
The answer for 21.5 as a fraction is 43/2.
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, 21.5 is the number on the numerator, and the base number 1 will be the denominator. Then, 21.5 becomes 21.5/1.
