How do you turn 3.285714 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.285714 repeating into a fraction, begin writing this simple equation:

n = 3.285714 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (85714) and 1 digit in the non-repeating part (2). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 3285714.85714 (equation 2)

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

1000000 × n = 3285714.85714
     10 × n = 3.285714
 999990 × n = 3285682

3285682999990 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 = 3285682999990 = 3285682 ÷ 2999990 ÷ 2 = 1642841499995. So,
