Is 2/3 a terminating decimal?




Here we will show you how to determine if 2/3 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 2/3 (2 ÷ 3) is terminating or non-terminating.

Here are the steps to determine if 2/3 is a terminating decimal number:

1) Find the denominator of 2/3 in its lowest form.
The greatest common factor (GCF) of 2 and 3 is 1. Convert 2/3 to its simplest form by dividing the numerator and denominator by its GCF:

   
2 ÷ 1
 
   
3 ÷ 1
 
  = 
   
2
 
   
3
 
   

Thus, the denominator of 2/3 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 2/3 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:

2/3
= non-terminating
