How do you turn 0.2007692 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.2007692 repeating into a fraction, begin writing this simple equation:

n = 0.2007692 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (07692) and 2 digits in the non-repeating part (20). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 2007692.07692 (equation 2)

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

10000000 × n = 2007692.07692
     100 × n = 0.2007692
 9999900 × n = 2007672

20076729999900 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 = 20076729999900 = 2007672 ÷ 129999900 ÷ 12 = 167306833325. So,

0.2007692 = 167306833325 as the lowest possible fraction.
