How do you turn 11.143846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.143846 repeating into a fraction, begin writing this simple equation:

n = 11.143846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 2 digits in the non-repeating part (14). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 11143846.3846 (equation 2)

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

1000000 × n = 11143846.3846
    100 × n = 11.143846
 999900 × n = 11142732

11142732999900 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 12 (the GCF - greatest common factor).

n = 11142732999900 = 11142732 ÷ 12999900 ÷ 12 = 92856183325. So,

11.143846 = 92856183325 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 92856183325 is also equal to 111198683325 when expressed as a mixed number.
