How do you turn 16.13153 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.13153 repeating into a fraction, begin writing this simple equation:

n = 16.13153 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (153) and 2 digits in the non-repeating part (13). Multiply both sides by 10⁵ = 100000.

100000 × n = 1613153.153 (equation 2)

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

100000 × n = 1613153.153
   100 × n = 16.13153
 99900 × n = 1611540

161154099900 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 180 (the GCF - greatest common factor).

n = 161154099900 = 1611540 ÷ 18099900 ÷ 180 = 8953555. So,

16.13153 = 8953555 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 8953555 is also equal to 1673555 when expressed as a mixed number.
