How do you turn 2.263076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.263076 repeating into a fraction, begin writing this simple equation:

n = 2.263076 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3076) and 2 digits in the non-repeating part (26). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 2263076.3076 (equation 2)

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

1000000 × n = 2263076.3076
    100 × n = 2.263076
 999900 × n = 2262850

2262850999900 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 50 (the GCF - greatest common factor).

n = 2262850999900 = 2262850 ÷ 50999900 ÷ 50 = 4525719998. So,

2.263076 = 4525719998 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 4525719998 is also equal to 2526119998 when expressed as a mixed number.
