Recurring decimals
Grade 9
By Mr Tono
Converting recurring decimals to
fractions
 Converting recurring decimals to fractions is representing a recurring decimal as a
fraction without changing its value.
 A recurring decimal is a decimal number that has a digit (or group of digits) that
repeats forever. The part that repeats can also be shown by placing dots over the first
and last digits of the repeating pattern.
 E.g.
are all recurring decimals
How to convert recurring decimals to fractions
Example 1
 Convert 0. 1 to a fraction
0. 1 = 𝑥 Equation 1
Because 0. 1 = 𝑥 has one repeating digit, we will multiply by 10
0. 1 × 10 = 1. 1
Remember because you are multiplying the whole of Equation 1 you also need to
multiply the variable 𝑥 by 10 (see below)
0. 1 = 𝑥 Equation 1
0. 1 × 10 = 𝑥 × 10
1. 1 = 10𝑥 Equation 2
1. 1 = 10𝑥 Equation 2
0. 1 = 𝑥 Equation 1
1 = 9𝑥
1 = 9𝑥
1

= 𝑥
