  3. The result: As we can see, dividing 8 by 7 leads to a recurring decimal, 1.142857 which continues infinitely.

The Nature of Recurring Decimals

The decimal representation of 8/7 is a recurring decimal, also known as a repeating decimal. This means that the decimal part of the number repeats in a specific pattern. In this case, the pattern is “142857”.

Why do some fractions become recurring decimals? It all comes down to the relationship between the numerator and denominator. If the denominator has a prime factor that is not 2 or 5 – the only prime factors of 10 – the decimal representation of the fraction will be recurring.

In this case, 7 is a prime number itself and it is not 2 or 5. This is why the decimal representation of 8/7 is a recurring decimal.

Understanding Recurring Decimals

Recurring decimals can seem daunting at first, but they are simply another way to represent fractions. They represent a number that can be written as a finite fraction, but in decimal form, the digits after the decimal point repeat indefinitely. This type of decimal can be described by placing a bar over the repeating block of digits, for example, 1.142857… can be written as 1.142857.
