What is 5.61333... as a Fraction?

5.613 equals 42175 as a fraction.

How do you turn 5.613 repeating into a fraction?

Detailed Answer:

Step 1: To convert 5.613 repeating into a fraction, begin writing this simple equation:

n = 5.613 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (61). Multiply both sides by 10³ = 1000.

1000 × n = 5613.3 (equation 2)

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

1000 × n = 5613.3
 100 × n = 5.613
 900 × n = 5052

5052900 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 12 (the GCF - greatest common factor).

n = 5052900 = 5052 ÷ 12900 ÷ 12 = 42175. So,

5.613 = 42175 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 42175 is also equal to 54675 when expressed as a mixed number.

The repeating decimal 5.613 (vinculum notation) has a repeated block length of 1. It is also represented as 5.61333... (ellipsis notation) which equals approximately 5.6133333 (decimal approximation)(*).

The recurring decimal 5.613 can be written as a ratio of two integers having 421 as the numerator and 75 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.
