How do you turn 13.2483 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.2483 repeating into a fraction, begin writing this simple equation:

n = 13.2483 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 2 digits in the non-repeating part (24). Multiply both sides by 10⁴ = 10000.

10000 × n = 132483.83 (equation 2)

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

10000 × n = 132483.83
  100 × n = 13.2483
 9900 × n = 131159

n = 1311599900 (answer)
