What is 1.105222... as a Fraction?

1.1052 equals 99479000 as a fraction.

How do you turn 1.1052 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.1052 repeating into a fraction, begin writing this simple equation:

n = 1.1052 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (2) and 3 digits in the non-repeating part (105). Multiply both sides by 10⁴ = 10000.

10000 × n = 11052.2 (equation 2)

Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.

10000 × n = 11052.2
 1000 × n = 1.1052
 9000 × n = 9947

n = 99479000 (answer)

1.1052 = 99479000 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 99479000 is also equal to 19479000 when expressed as a mixed number.

The repeating decimal 1.1052 (vinculum notation) has a repeated block length of 1. It is also represented as 1.105222... (ellipsis notation) which equals approximately 1.10522222 (decimal approximation)(*).
