Here we will show you how to determine if 5/7 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 5/7 (5 ÷ 7) is terminating or non-terminating.
Here are the steps to determine if 5/7 is a terminating decimal number:
1) Find the denominator of 5/7 in its lowest form.
The greatest common factor (GCF) of 5 and 7 is 1. Convert 5/7 to its simplest form by dividing the numerator and denominator by its GCF:
Thus, the denominator of 5/7 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:
3) Determine if 5/7 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:
