How do you turn 0.13846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.13846 repeating into a fraction, begin writing this simple equation:

n = 0.13846 (equation 1)

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

100000 × n = 13846.3846 (equation 2)

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

100000 × n = 13846.3846
    10 × n = 0.13846
 99990 × n = 13845

1384599990 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 15 (the GCF - greatest common factor).

n = 1384599990 = 13845 ÷ 1599990 ÷ 15 = 9236666. So,

0.13846 = 9236666 as the lowest possible fraction.
