How do you turn 1.33076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.33076 repeating into a fraction, begin writing this simple equation:

n = 1.33076 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3076) and 1 digit in the non-repeating part (3). Multiply both sides by 10⁵ = 100000.

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

100000 × n = 133076.3076
    10 × n = 1.33076
 99990 × n = 133063

n = 13306399990 (answer)
