How do you turn 0.143846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.143846 repeating into a fraction, begin writing this simple equation:

n = 0.143846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 2 digits in the non-repeating part (14). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 143846.3846 (equation 2)

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

1000000 × n = 143846.3846
    100 × n = 0.143846
 999900 × n = 143832

143832999900 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 12 (the GCF - greatest common factor).

n = 143832999900 = 143832 ÷ 12999900 ÷ 12 = 1198683325. So,

0.143846 = 1198683325 as the lowest possible fraction.
