What is 16.30555... as a Fraction?

16.305 equals 58736 as a fraction.

How do you turn 16.305 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.305 repeating into a fraction, begin writing this simple equation:

n = 16.305 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (5) and 2 digits in the non-repeating part (30). Multiply both sides by 10³ = 1000.

1000 × n = 16305.5 (equation 2)

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

1000 × n = 16305.5
 100 × n = 16.305
 900 × n = 14675

14675900 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 25 (the GCF - greatest common factor).

n = 14675900 = 14675 ÷ 25900 ÷ 25 = 58736. So,

16.305 = 58736 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 58736 is also equal to 161136 when expressed as a mixed number.

The repeating decimal 16.305 (vinculum notation) has a repeated block length of 1. It is also represented as 16.30555... (ellipsis notation) which equals approximately 16.3055555 (decimal approximation)(*).

The recurring decimal 16.305 can be written as a ratio of two integers having 587 as the numerator and 36 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.
