Here we will show you how to determine if 5/8 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 5/8 (5 ÷ 8) is repeating or non-repeating.
Here are the steps to determine if 5/8 is a repeating decimal number:
1) Find the denominator of 5/8 in its lowest form.
The greatest common factor (GCF) of 5 and 8 is 1. Convert 5/8 to its simplest form by dividing the numerator and denominator by its GCF:
Thus, the denominator of 5/8 in its lowest form is 8.
2) Find the prime factors of the answer in Step 1.
The prime factors of 8 are all the prime numbers that you multiply together to get 8. The prime factors of 8 are:
2 x 2 x 2
3) Determine if 5/8 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:
