What is 1.03888... as a Fraction?

1.038 equals 187180 as a fraction.

How do you turn 1.038 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.038 repeating into a fraction, begin writing this simple equation:

n = 1.038 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 2 digits in the non-repeating part (03). Multiply both sides by 10³ = 1000.

1000 × n = 1038.8 (equation 2)

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

1000 × n = 1038.8
 100 × n = 1.038
 900 × n = 935

935900 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 5 (the GCF - greatest common factor).

n = 935900 = 935 ÷ 5900 ÷ 5 = 187180. So,

1.038 = 187180 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 187180 is also equal to 17180 when expressed as a mixed number.

The repeating decimal 1.038 (vinculum notation) has a repeated block length of 1. It is also represented as 1.03888... (ellipsis notation) which equals approximately 1.0388888 (decimal approximation)(*).

The recurring decimal 1.038 can be written as a ratio of two integers having 187 as the numerator and 180 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.
