What is 43.11666... as a Fraction?

43.116 equals 258760 as a fraction.

How do you turn 43.116 repeating into a fraction?

Detailed Answer:

Step 1: To convert 43.116 repeating into a fraction, begin writing this simple equation:

n = 43.116 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (11). Multiply both sides by 10³ = 1000.

1000 × n = 43116.6 (equation 2)

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

1000 × n = 43116.6
 100 × n = 43.116
 900 × n = 38805

38805900 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 = 38805900 = 38805 ÷ 15900 ÷ 15 = 258760. So,

43.116 = 258760 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 258760 is also equal to 43760 when expressed as a mixed number.

The repeating decimal 43.116 (vinculum notation) has a repeated block length of 1. It is also represented as 43.11666... (ellipsis notation) which equals approximately 43.1166666 (decimal approximation)(*).

The recurring decimal 43.116 can be written as a ratio of two integers having 2587 as the numerator and 60 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.
