How do you turn 11.4461 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.4461 repeating into a fraction, begin writing this simple equation:

n = 11.4461 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (461) and 1 digit in the non-repeating part (4). Multiply both sides by 10⁴ = 10000.

10000 × n = 114461.461 (equation 2)

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

10000 × n = 114461.461
   10 × n = 11.4461
 9990 × n = 114347

n = 1143479990 (answer)
