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.

Step 2: To remove the decimal from the fraction, you need to multiply both the numerator and the denominator by 10 (because there is only 1 decimal place). 21.5/1 × 10/10 = 215/10

Step 3: Here, 5 is the GCD of 215 and 10. Now, to make the fraction simpler, divide the numerator and denominator by 5. 215/10 = 43/2 Hence, 21.5 in the form of a fraction is 43/2.

Thus, 21.5 can be written as a fraction 43/2.
