Is 3/15 a terminating decimal?

Here we will show you how to determine if 3/15 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 3/15 (3 ÷ 15) is terminating or non-terminating.

Here are the steps to determine if 3/15 is a terminating decimal number:

1) Find the denominator of 3/15 in its lowest form.
The greatest common factor (GCF) of 3 and 15 is 3. Convert 3/15 to its simplest form by dividing the numerator and denominator by its GCF:

		3 ÷ 3
		15 ÷ 3

		1
		5

Thus, the denominator of 3/15 in its lowest form is 5.

2) Find the prime factors of the answer in Step 1.
The prime factors of 5 are all the prime numbers that you multiply together to get 5. The prime factors of 5 are:

5

3) Determine if 3/15 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:

3/15
= terminating
