What is 0.11285285285... as a Fraction?

0.11285 equals 187916650 as a fraction.

How do you turn 0.11285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.11285 repeating into a fraction, begin writing this simple equation:

n = 0.11285 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (285) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁵ = 100000.

100000 × n = 11285.285 (equation 2)

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

100000 × n = 11285.285
   100 × n = 0.11285
 99900 × n = 11274

1127499900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 6 (the GCF - greatest common factor).

n = 1127499900 = 11274 ÷ 699900 ÷ 6 = 187916650. So,

0.11285 = 187916650 as the lowest possible fraction.
