Is 86/43 a repeating decimal?

Here we will show you how to determine if 86/43 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 86/43 (86 ÷ 43) is repeating or non-repeating.

Here are the steps to determine if 86/43 is a repeating decimal number:

1) Find the denominator of 86/43 in its lowest form.
The greatest common factor (GCF) of 86 and 43 is 43. Convert 86/43 to its simplest form by dividing the numerator and denominator by its GCF:

		86 ÷ 43
		43 ÷ 43

		2
		1

Thus, the denominator of 86/43 in its lowest form is 1.

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

none

3) Determine if 86/43 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 not the case here, which means that our answer is as follows:

86/43
= non-repeating
