How do you turn 2.9384 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.9384 repeating into a fraction, begin writing this simple equation:

n = 2.9384 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (384) and 1 digit in the non-repeating part (9). Multiply both sides by 10⁴ = 10000.

10000 × n = 29384.384 (equation 2)

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

10000 × n = 29384.384
   10 × n = 2.9384
 9990 × n = 29355

293559990 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 15 (the GCF - greatest common factor).

n = 293559990 = 29355 ÷ 159990 ÷ 15 = 1957666. So,

2.9384 = 1957666 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 1957666 is also equal to 2625666 when expressed as a mixed number.

The repeating decimal 2.9384 (vinculum notation) has a repeated block length of 3. It is also represented as 2.9384384384... (ellipsis notation) which equals approximately 2.9384384384384384 (decimal approximation)(*).

The recurring decimal 2.9384 can be written as a ratio of two integers having 1957 as the numerator and 666 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.
