How do you turn 16.25714 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.25714 repeating into a fraction, begin writing this simple equation:

n = 16.25714 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (5714) and 1 digit in the non-repeating part (2). Multiply both sides by 10⁵ = 100000.

100000 × n = 1625714.5714 (equation 2)

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

100000 × n = 1625714.5714
    10 × n = 16.25714
 99990 × n = 1625552

162555299990 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 2 (the GCF - greatest common factor).

n = 162555299990 = 1625552 ÷ 299990 ÷ 2 = 81277649995. So,

16.25714 = 81277649995 as the lowest possible fraction.
