Is 2/9 a repeating decimal?

Here we will show you how to determine if 2/9 is a repeating decimal or a non-repeating decimal.

A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 2/9 (2 ÷ 9) is repeating or non-repeating.

Here are the steps to determine if 2/9 is a repeating decimal number:

1) Find the denominator of 2/9 in its lowest form.
The greatest common factor (GCF) of 2 and 9 is 1. Convert 2/9 to its simplest form by dividing the numerator and denominator by its GCF:

		2 ÷ 1
		9 ÷ 1

		2
		9

Thus, the denominator of 2/9 in its lowest form is 9.

2) Find the prime factors of the answer in Step 1.
The prime factors of 9 are all the prime numbers that you multiply together to get 9. The prime factors of 9 are:

3 x 3

3) Determine if 2/9 is repeating
A fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:

2/9
= repeating
