What is 2.35292929... as a Fraction?

2.3529 equals 116474950 as a fraction.

How do you turn 2.3529 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.3529 repeating into a fraction, begin writing this simple equation:

n = 2.3529 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (29) and 2 digits in the non-repeating part (35). Multiply both sides by 10⁴ = 10000.

10000 × n = 23529.29 (equation 2)

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

10000 × n = 23529.29
  100 × n = 2.3529
 9900 × n = 23294

232949900 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 2 (the GCF - greatest common factor).

n = 232949900 = 23294 ÷ 29900 ÷ 2 = 116474950. So,

2.3529 = 116474950 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 116474950 is also equal to 217474950 when expressed as a mixed number.

The repeating decimal 2.3529 (vinculum notation) has a repeated block length of 2. It is also represented as 2.35292929... (ellipsis notation) which equals approximately 2.352929292929 (decimal approximation)(*).

The recurring decimal 2.3529 can be written as a ratio of two integers having 11647 as the numerator and 4950 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
