What is 73.3666... as a Fraction?

73.36 equals 220130 as a fraction.

How do you turn 73.36 repeating into a fraction?

Detailed Answer:

Step 1: To convert 73.36 repeating into a fraction, begin writing this simple equation:

n = 73.36 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 1 digit in the non-repeating part (3). Multiply both sides by 10² = 100.

100 × n = 7336.6 (equation 2)

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

100 × n = 7336.6
 10 × n = 73.36
 90 × n = 6603

660390 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 3 (the GCF - greatest common factor).

n = 660390 = 6603 ÷ 390 ÷ 3 = 220130. So,

73.36 = 220130 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 220130 is also equal to 731130 when expressed as a mixed number.

The repeating decimal 73.36 (vinculum notation) has a repeated block length of 1. It is also represented as 73.3666... (ellipsis notation) which equals approximately 73.366666 (decimal approximation)(*).

The recurring decimal 73.36 can be written as a ratio of two integers having 2201 as the numerator and 30 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.
