What is 50.6444... as a Fraction?

50.64 equals 227945 as a fraction.

How do you turn 50.64 repeating into a fraction?

Detailed Answer:

Step 1: To convert 50.64 repeating into a fraction, begin writing this simple equation:

n = 50.64 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (4) and 1 digit in the non-repeating part (6). Multiply both sides by 10² = 100.

100 × n = 5064.4 (equation 2)

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

100 × n = 5064.4
 10 × n = 50.64
 90 × n = 4558

455890 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 2 (the GCF - greatest common factor).

n = 455890 = 4558 ÷ 290 ÷ 2 = 227945. So,

50.64 = 227945 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 227945 is also equal to 502945 when expressed as a mixed number.

The repeating decimal 50.64 (vinculum notation) has a repeated block length of 1. It is also represented as 50.6444... (ellipsis notation) which equals approximately 50.644444 (decimal approximation)(*).

The recurring decimal 50.64 can be written as a ratio of two integers having 2279 as the numerator and 45 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.
