What is 97.6111... as a Fraction?

97.61 equals 175718 as a fraction.

How do you turn 97.61 repeating into a fraction?

Detailed Answer:

Step 1: To convert 97.61 repeating into a fraction, begin writing this simple equation:

n = 97.61 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (1) and 1 digit in the non-repeating part (6). Multiply both sides by 10² = 100.

100 × n = 9761.1 (equation 2)

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

100 × n = 9761.1
 10 × n = 97.61
 90 × n = 8785

878590 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 5 (the GCF - greatest common factor).

n = 878590 = 8785 ÷ 590 ÷ 5 = 175718. So,

97.61 = 175718 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 175718 is also equal to 971118 when expressed as a mixed number.

The repeating decimal 97.61 (vinculum notation) has a repeated block length of 1. It is also represented as 97.6111... (ellipsis notation) which equals approximately 97.611111 (decimal approximation)(*).

The recurring decimal 97.61 can be written as a ratio of two integers having 1757 as the numerator and 18 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.
