Is 2/8 a terminating decimal?

Here we will show you how to determine if 2/8 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 2/8 (2 ÷ 8) is terminating or non-terminating.

Here are the steps to determine if 2/8 is a terminating decimal number:

1) Find the denominator of 2/8 in its lowest form.
The greatest common factor (GCF) of 2 and 8 is 2. Convert 2/8 to its simplest form by dividing the numerator and denominator by its GCF:

		2 ÷ 2
		8 ÷ 2

		1
		4

Thus, the denominator of 2/8 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 2/8 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 the case here, which means that our answer is as follows:

2/8
= terminating
