How do you turn 0.18307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.18307 repeating into a fraction, begin writing this simple equation:

n = 0.18307 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (307) and 2 digits in the non-repeating part (18). Multiply both sides by 10⁵ = 100000.

100000 × n = 18307.307 (equation 2)

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

100000 × n = 18307.307
   100 × n = 0.18307
 99900 × n = 18289

n = 1828999900 (answer)
