How do you turn 5.102307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 5.102307 repeating into a fraction, begin writing this simple equation:

n = 5.102307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 2 digits in the non-repeating part (10). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 5102307.2307 (equation 2)

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

1000000 × n = 5102307.2307
    100 × n = 5.102307
 999900 × n = 5101797

5101797999900 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 3 (the GCF - greatest common factor).

n = 5101797999900 = 5101797 ÷ 3999900 ÷ 3 = 1700599333300. So,

5.102307 = 1700599333300 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 1700599333300 is also equal to 534099333300 when expressed as a mixed number.
