How do you turn 14.142 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.142 repeating into a fraction, begin writing this simple equation:

n = 14.142 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (142), so multiply both sides by 10³ = 1000.

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

1000 × n = 14142.142
   1 × n = 14.142
 999 × n = 14128

n = 700014995 (answer)
