What is 53.1766... as a Fraction?

53.176 equals 15953300 as a fraction.

How do you turn 53.176 repeating into a fraction?

Detailed Answer:

Step 1: To convert 53.176 repeating into a fraction, begin writing this simple equation:

n = 53.176 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (17). Multiply both sides by 10³ = 1000.

1000 × n = 53176.6 (equation 2)

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

1000 × n = 53176.6
 100 × n = 53.176
 900 × n = 47859

47859900 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 = 47859900 = 47859 ÷ 3900 ÷ 3 = 15953300. So,

53.176 = 15953300 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 15953300 is also equal to 5353300 when expressed as a mixed number.

The repeating decimal 53.176 (vinculum notation) has a repeated block length of 1. It is also represented as 53.17666... (ellipsis notation) which equals approximately 53.1766666 (decimal approximation)(*).

The recurring decimal 53.176 can be written as a ratio of two integers having 15953 as the numerator and 300 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.
