What is 10.97222... as a Fraction?

10.972 equals 39536 as a fraction.

How do you turn 10.972 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.972 repeating into a fraction, begin writing this simple equation:

n = 10.972 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (2) and 2 digits in the non-repeating part (97). Multiply both sides by 10³ = 1000.

1000 × n = 10972.2 (equation 2)

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

1000 × n = 10972.2
 100 × n = 10.972
 900 × n = 9875

9875900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 25 (the GCF - greatest common factor).

n = 9875900 = 9875 ÷ 25900 ÷ 25 = 39536. So,

10.972 = 39536 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 39536 is also equal to 103536 when expressed as a mixed number.

The repeating decimal 10.972 (vinculum notation) has a repeated block length of 1. It is also represented as 10.97222... (ellipsis notation) which equals approximately 10.9722222 (decimal approximation)(*).

The recurring decimal 10.972 can be written as a ratio of two integers having 395 as the numerator and 36 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
