What is 0.35230230230... as a Fraction?

0.35230 equals 703919980 as a fraction.

How do you turn 0.35230 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.35230 repeating into a fraction, begin writing this simple equation:

n = 0.35230 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (230) and 2 digits in the non-repeating part (35). Multiply both sides by 10⁵ = 100000.

100000 × n = 35230.230 (equation 2)

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

100000 × n = 35230.230
   100 × n = 0.35230
 99900 × n = 35195

3519599900 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 5 (the GCF - greatest common factor).

n = 3519599900 = 35195 ÷ 599900 ÷ 5 = 703919980. So,

0.35230 = 703919980 as the lowest possible fraction.

The repeating decimal 0.35230 (vinculum notation) has a repeated block length of 3. It is also represented as 0.35230230230... (ellipsis notation) which equals approximately 0.35230230230230230 (decimal approximation)(*).
