What is 1.8828282... as a Fraction?

1.882 equals 932495 as a fraction.

How do you turn 1.882 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.882 repeating into a fraction, begin writing this simple equation:

n = 1.882 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (82) and 1 digit in the non-repeating part (8). Multiply both sides by 10³ = 1000.

1000 × n = 1882.82 (equation 2)

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

1000 × n = 1882.82
  10 × n = 1.882
 990 × n = 1864

1864990 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 = 1864990 = 1864 ÷ 2990 ÷ 2 = 932495. So,

1.882 = 932495 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 932495 is also equal to 1437495 when expressed as a mixed number.

The repeating decimal 1.882 (vinculum notation) has a repeated block length of 2. It is also represented as 1.8828282... (ellipsis notation) which equals approximately 1.88282828282 (decimal approximation)(*).

The recurring decimal 1.882 can be written as a ratio of two integers having 932 as the numerator and 495 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.
