What is 2.642 as a fraction?

Numbers can be represented in a variety of ways including percentages, decimals, and fractions. The ability to convert any number from one format to another is an important math skill to have. These skills are typically thought in fifth grade math and require an understanding of place values and Greatest Common Factor (GCF).

In this article, we teach those skills step by step while demonstrating how to convert decimal 2.642 into a fraction.

Answer: 2.642 as a fraction equals 2642/1000 or 1321/500

Here is the solution for converting 2.642 to a fraction:

Step 1:

First, we write 2.642 as  

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point. Remember the numerator is the top part of the fraction and the denominator is the bottom part!
2.642 x 1000/1 x 1000

Step 3:

Next, we find the Greatest Common Factor (GCF) for 2642 and 1000. A factor is a number that divides into another number without any remainder.

The factors of 2642 are: 1  2  1321  2642 
The factors of 1000 are: 1  2  4  5  8  10  20  25  40  50  100  125  200  250  500  1000 
So for 2642 and 1000 that gives us a GCF value of: 2

Step 4:

For the last step we reduce the fraction. This just means writing the fraction in the simplest way. To do this we divide both the numerator and denominator by the GCF value we determined in step 3.
2642 ÷ 2/1000 ÷ 2

Good work! We have just walked through the steps on how to represent 2.642 as a fraction.
