Is 66/88 a repeating decimal?

Here we will show you how to determine if 66/88 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 66/88 (66 ÷ 88) is repeating or non-repeating.

Here are the steps to determine if 66/88 is a repeating decimal number:

1) Find the denominator of 66/88 in its lowest form.
The greatest common factor (GCF) of 66 and 88 is 22. Convert 66/88 to its simplest form by dividing the numerator and denominator by its GCF:

		66 ÷ 22
		88 ÷ 22

		3
		4

Thus, the denominator of 66/88 in its lowest form is 4.

2) Find the prime factors of the answer in Step 1.
The prime factors of 4 are all the prime numbers that you multiply together to get 4. The prime factors of 4 are:

2 x 2

3) Determine if 66/88 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:

66/88
= non-repeating
