How do you turn 1.3384 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.3384 repeating into a fraction, begin writing this simple equation:

n = 1.3384 (equation 1)

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

10000 × n = 13384.384 (equation 2)

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

10000 × n = 13384.384
   10 × n = 1.3384
 9990 × n = 13371

133719990 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 3 (the GCF - greatest common factor).

n = 133719990 = 13371 ÷ 39990 ÷ 3 = 44573330. So,

1.3384 = 44573330 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 44573330 is also equal to 111273330 when expressed as a mixed number.

The repeating decimal 1.3384 (vinculum notation) has a repeated block length of 3. It is also represented as 1.3384384384... (ellipsis notation) which equals approximately 1.3384384384384384 (decimal approximation)(*).

The recurring decimal 1.3384 can be written as a ratio of two integers having 4457 as the numerator and 3330 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.
