How do you turn 16.24285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.24285 repeating into a fraction, begin writing this simple equation:

n = 16.24285 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (285) and 2 digits in the non-repeating part (24). Multiply both sides by 10⁵ = 100000.

100000 × n = 1624285.285 (equation 2)

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

100000 × n = 1624285.285
   100 × n = 16.24285
 99900 × n = 1622661

162266199900 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 3 (the GCF - greatest common factor).

n = 162266199900 = 1622661 ÷ 399900 ÷ 3 = 54088733300. So,

16.24285 = 54088733300 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 54088733300 is also equal to 16808733300 when expressed as a mixed number.
