How do you turn 10.2307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.2307 repeating into a fraction, begin writing this simple equation:

n = 10.2307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307), so multiply both sides by 10⁴ = 10000.

10000 × n = 102307.2307 (equation 2)

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

10000 × n = 102307.2307
    1 × n = 10.2307
 9999 × n = 102297

1022979999 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 = 1022979999 = 102297 ÷ 39999 ÷ 3 = 340993333. So,

10.2307 = 340993333 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 340993333 is also equal to 107693333 when expressed as a mixed number.
