How do you turn 4.113076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 4.113076 repeating into a fraction, begin writing this simple equation:

n = 4.113076 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3076) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 4113076.3076 (equation 2)

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

1000000 × n = 4113076.3076
    100 × n = 4.113076
 999900 × n = 4112665

4112665999900 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 5 (the GCF - greatest common factor).

n = 4112665999900 = 4112665 ÷ 5999900 ÷ 5 = 822533199980. So,

4.113076 = 822533199980 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 822533199980 is also equal to 422613199980 when expressed as a mixed number.
