How do you turn 14.16384 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.16384 repeating into a fraction, begin writing this simple equation:

n = 14.16384 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (384) and 2 digits in the non-repeating part (16). Multiply both sides by 10⁵ = 100000.

100000 × n = 1416384.384 (equation 2)

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

100000 × n = 1416384.384
   100 × n = 14.16384
 99900 × n = 1414968

141496899900 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 = 141496899900 = 1414968 ÷ 1299900 ÷ 12 = 1179148325. So,

14.16384 = 1179148325 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 1179148325 is also equal to 1413648325 when expressed as a mixed number.
