A fraction represents a whole and a fractional part. Decimals represent the fractional part of numbers. For example, 1/2. Numbers in decimal form are expressed with a decimal point (.), for example, 2.1. We are going to learn how to convert a decimal to a fraction.

What is 2.1 as a Fraction?

Answer

The answer for 2.1 as a fraction is 21/10.

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, 2.1 is the number on the numerator and the base number 1 will be the denominator. Then, 2.1 becomes 2.1/1.

Step 2: To remove the decimal from a fraction, you need to multiply both the numerator and denominator by 10 (because there is only 1 decimal place). 2.1/1 × 10/10 = 21/10

Step 3: Since 21 and 10 do not have any common factors other than 1, the fraction is already in its simplest form.

Thus, 2.1 can be written as a fraction 21/10.
