How do you turn 5.34384 repeating into a fraction?

Detailed Answer:

Step 1: To convert 5.34384 repeating into a fraction, begin writing this simple equation:

n = 5.34384 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (384) and 2 digits in the non-repeating part (34). Multiply both sides by 10⁵ = 100000.

100000 × n = 534384.384 (equation 2)

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

100000 × n = 534384.384
   100 × n = 5.34384
 99900 × n = 533850

53385099900 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 150 (the GCF - greatest common factor).

n = 53385099900 = 533850 ÷ 15099900 ÷ 150 = 3559666. So,

5.34384 = 3559666 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 3559666 is also equal to 5229666 when expressed as a mixed number.

The repeating decimal 5.34384 (vinculum notation) has a repeated block length of 3. It is also represented as 5.34384384384... (ellipsis notation) which equals approximately 5.34384384384384384 (decimal approximation)(*).
