What is 167.2777... as a Fraction?

167.27 equals 301118 as a fraction.

How do you turn 167.27 repeating into a fraction?

Detailed Answer:

Step 1: To convert 167.27 repeating into a fraction, begin writing this simple equation:

n = 167.27 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7) and 1 digit in the non-repeating part (2). Multiply both sides by 10² = 100.

100 × n = 16727.7 (equation 2)

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

100 × n = 16727.7
 10 × n = 167.27
 90 × n = 15055

1505590 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 = 1505590 = 15055 ÷ 590 ÷ 5 = 301118. So,

167.27 = 301118 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 301118 is also equal to 167518 when expressed as a mixed number.

The repeating decimal 167.27 (vinculum notation) has a repeated block length of 1. It is also represented as 167.2777... (ellipsis notation) which equals approximately 167.277777 (decimal approximation)(*).

The recurring decimal 167.27 can be written as a ratio of two integers having 3011 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.
