How do you turn 2.303076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.303076 repeating into a fraction, begin writing this simple equation:

n = 2.303076 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3076) and 2 digits in the non-repeating part (30). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 2303076.3076 (equation 2)

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

1000000 × n = 2303076.3076
    100 × n = 2.303076
 999900 × n = 2302846

2302846999900 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 2 (the GCF - greatest common factor).

n = 2302846999900 = 2302846 ÷ 2999900 ÷ 2 = 1151423499950. So,

2.303076 = 1151423499950 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 1151423499950 is also equal to 2151523499950 when expressed as a mixed number.
