Is 7/49 a terminating decimal?

Here we will show you how to determine if 7/49 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 7/49 (7 ÷ 49) is terminating or non-terminating.

Here are the steps to determine if 7/49 is a terminating decimal number:

1) Find the denominator of 7/49 in its lowest form.
The greatest common factor (GCF) of 7 and 49 is 7. Convert 7/49 to its simplest form by dividing the numerator and denominator by its GCF:

		7 ÷ 7
		49 ÷ 7

		1
		7

Thus, the denominator of 7/49 in its lowest form is 7.

2) Find the prime factors of the answer in Step 1.
The prime factors of 7 are all the prime numbers that you multiply together to get 7. The prime factors of 7 are:

7

3) Determine if 7/49 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:

7/49
= non-terminating
