How do you turn 2.114285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.114285 repeating into a fraction, begin writing this simple equation:

n = 2.114285 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (14285) and 1 digit in the non-repeating part (1). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 2114285.14285 (equation 2)

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

1000000 × n = 2114285.14285
     10 × n = 2.114285
 999990 × n = 2114264

2114264999990 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 = 2114264999990 = 2114264 ÷ 2999990 ÷ 2 = 1057132499995. So,
