What is 0.28076076076... as a Fraction?

0.28076 equals 701224975 as a fraction.

How do you turn 0.28076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.28076 repeating into a fraction, begin writing this simple equation:

n = 0.28076 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (076) and 2 digits in the non-repeating part (28). Multiply both sides by 10⁵ = 100000.

100000 × n = 28076.076 (equation 2)

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

100000 × n = 28076.076
   100 × n = 0.28076
 99900 × n = 28048

2804899900 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 4 (the GCF - greatest common factor).

n = 2804899900 = 28048 ÷ 499900 ÷ 4 = 701224975. So,

0.28076 = 701224975 as the lowest possible fraction.
