How do you turn 14.130769 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.130769 repeating into a fraction, begin writing this simple equation:

n = 14.130769 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (0769) and 2 digits in the non-repeating part (13). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 14130769.0769 (equation 2)

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

1000000 × n = 14130769.0769
    100 × n = 14.130769
 999900 × n = 14129356

14129356999900 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 = 14129356999900 = 14129356 ÷ 4999900 ÷ 4 = 3532339249975. So,

14.130769 = 3532339249975 as the lowest possible fraction.
