Is 31/93 a terminating decimal?

Here we will show you how to determine if 31/93 is a terminating decimal or a non-terminating decimal.

A terminating decimal is a decimal number that has a finite number of decimals and does not go on indefinitely. We want to know if the decimal number you get when you divide the fraction 31/93 (31 ÷ 93) is terminating or non-terminating.

Here are the steps to determine if 31/93 is a terminating decimal number:

1) Find the denominator of 31/93 in its lowest form.
The greatest common factor (GCF) of 31 and 93 is 31. Convert 31/93 to its simplest form by dividing the numerator and denominator by its GCF:

		31 ÷ 31
		93 ÷ 31

		1
		3

Thus, the denominator of 31/93 in its lowest form is 3.

2) Find the prime factors of the answer in Step 1.
The prime factors of 3 are all the prime numbers that you multiply together to get 3. The prime factors of 3 are:

3

3) Determine if 31/93 is terminating
A fraction is a terminating decimal if the prime factors of the denominator of the fraction in its lowest form only contain 2s and/or 5s or no prime factors at all. This is not the case here, which means that our answer is as follows:

31/93
= non-terminating
