How do you turn 0.153846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.153846 repeating into a fraction, begin writing this simple equation:

n = 0.153846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 2 digits in the non-repeating part (15). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 153846.3846 (equation 2)

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

1000000 × n = 153846.3846
    100 × n = 0.153846
 999900 × n = 153831

153831999900 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 = 153831999900 = 153831 ÷ 3999900 ÷ 3 = 51277333300. So,

0.153846 = 51277333300 as the lowest possible fraction.
