What is 0.11828282... as a Fraction?

0.1182 equals 11719900 as a fraction.

How do you turn 0.1182 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.1182 repeating into a fraction, begin writing this simple equation:

n = 0.1182 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (82) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁴ = 10000.

10000 × n = 1182.82 (equation 2)

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

10000 × n = 1182.82
  100 × n = 0.1182
 9900 × n = 1171

n = 11719900 (answer)

0.1182 = 11719900 as the lowest possible fraction.
