3.23153 equals 35871110 as a fraction.

How do you turn 3.23153 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.23153 repeating into a fraction, begin writing this simple equation:

n = 3.23153 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (153) and 2 digits in the non-repeating part (23). Multiply both sides by 10⁵ = 100000.

100000 × n = 323153.153 (equation 2)

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

100000 × n = 323153.153
   100 × n = 3.23153
 99900 × n = 322830

32283099900 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 90 (the GCF - greatest common factor).

n = 32283099900 = 322830 ÷ 9099900 ÷ 90 = 35871110. So,

3.23153 = 35871110 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 35871110 is also equal to 32571110 when expressed as a mixed number.

The repeating decimal 3.23153 (vinculum notation) has a repeated block length of 3. It is also represented as 3.23153153153... (ellipsis notation) which equals approximately 3.23153153153153153 (decimal approximation)(*).
