Is 4/8 a terminating decimal? Here we will show you how to determine if 4/8 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 4/8 (4 ÷ 8) is terminating or non-terminating.

Here are the steps to determine if 4/8 is a terminating decimal number:

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

 4 ÷ 4 8 ÷ 4
=
 1 2

Thus, the denominator of 4/8 in its lowest form is 2.

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

2

3) Determine if 4/8 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:

4/8
= terminating
