Why do you put a repeating decimal over 9?

Hi there, Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. The number of 9’s in the denominator should be the same as the number of digits in the repeated block.

Is 9 a repeating decimal?

In mathematics, 0.999… (also written as 0.9, in repeating decimal notation) denotes the repeating decimal consisting of an unending sequence of 9s after the decimal point. In other systems, 0.999… can have the same meaning, a different definition, or be undefined.

What is 0.9 recurring as a fraction?

0.9 represents the fraction 9/10, 0.25 the fraction 25/100 = 1/4. We can use terminating decimals to build up non-terminating decimals. Infinitely long decimals are a shorthand way to write out a sequence of finitely long terminating decimals.

How do you calculate recurring and non-recurring decimal places?

Step 1: Make your number equal to x. Step 2: Multiply both sides by extcolor {blue} {10} for each decimal place that isn’t recurring (If there are none, it stays as Step 1 ). Step 3: Multiply both sides by extcolor {blue} {10} for each number that is recurring.
