Is 8/12 a terminating decimal?

Here we will show you how to determine if 8/12 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 8/12 (8 ÷ 12) is terminating or non-terminating.

Here are the steps to determine if 8/12 is a terminating decimal number:

1) Find the denominator of 8/12 in its lowest form.
The greatest common factor (GCF) of 8 and 12 is 4. Convert 8/12 to its simplest form by dividing the numerator and denominator by its GCF:

		8 ÷ 4
		12 ÷ 4

		2
		3

Thus, the denominator of 8/12 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 8/12 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:

8/12
= non-terminating
