How do you turn 0.53846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.53846 repeating into a fraction, begin writing this simple equation:

n = 0.53846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 1 digit in the non-repeating part (5). Multiply both sides by 10⁵ = 100000.

100000 × n = 53846.3846 (equation 2)

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

100000 × n = 53846.3846
    10 × n = 0.53846
 99990 × n = 53841

5384199990 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 = 5384199990 = 53841 ÷ 399990 ÷ 3 = 1794733330. So,

0.53846 = 1794733330 as the lowest possible fraction.
