How do you turn 2.307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.307 repeating into a fraction, begin writing this simple equation:

n = 2.307 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (307), so multiply both sides by 10³ = 1000.

1000 × n = 2307.307 (equation 2)

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

1000 × n = 2307.307
   1 × n = 2.307
 999 × n = 2305

n = 202879990 (answer)
