How do you turn 16.16153 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.16153 repeating into a fraction, begin writing this simple equation:

n = 16.16153 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (153) and 2 digits in the non-repeating part (16). Multiply both sides by 10⁵ = 100000.

100000 × n = 1616153.153 (equation 2)

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

100000 × n = 1616153.153
   100 × n = 16.16153
 99900 × n = 1614537

161453799900 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 9 (the GCF - greatest common factor).

n = 161453799900 = 1614537 ÷ 999900 ÷ 9 = 17939311100. So,

16.16153 = 17939311100 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 17939311100 is also equal to 16179311100 when expressed as a mixed number.
