How do you turn 1.113846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.113846 repeating into a fraction, begin writing this simple equation:

n = 1.113846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 1113846.3846 (equation 2)

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

1000000 × n = 1113846.3846
    100 × n = 1.113846
 999900 × n = 1113735

1113735999900 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 15 (the GCF - greatest common factor).

n = 1113735999900 = 1113735 ÷ 15999900 ÷ 15 = 7424966660. So,

1.113846 = 7424966660 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 7424966660 is also equal to 1758966660 when expressed as a mixed number.
