How do you turn 0.134285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.134285 repeating into a fraction, begin writing this simple equation:

n = 0.134285 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (4285) and 2 digits in the non-repeating part (13). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 134285.4285 (equation 2)

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

1000000 × n = 134285.4285
    100 × n = 0.134285
 999900 × n = 134272

134272999900 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 4 (the GCF - greatest common factor).

n = 134272999900 = 134272 ÷ 4999900 ÷ 4 = 33568249975. So,

0.134285 = 33568249975 as the lowest possible fraction.
