What is 1.1461461461... as a Fraction?

1.1461 equals 1145999 as a fraction.

How do you turn 1.1461 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.1461 repeating into a fraction, begin writing this simple equation:

n = 1.1461 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (461) and 1 digit in the non-repeating part (1). Multiply both sides by 10⁴ = 10000.

10000 × n = 11461.461 (equation 2)

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

10000 × n = 11461.461
   10 × n = 1.1461
 9990 × n = 11450

114509990 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 10 (the GCF - greatest common factor).

n = 114509990 = 11450 ÷ 109990 ÷ 10 = 1145999. So,

1.1461 = 1145999 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 1145999 is also equal to 1146999 when expressed as a mixed number.

The repeating decimal 1.1461 (vinculum notation) has a repeated block length of 3. It is also represented as 1.1461461461... (ellipsis notation) which equals approximately 1.1461461461461461 (decimal approximation)(*).

The recurring decimal 1.1461 can be written as a ratio of two integers having 1145 as the numerator and 999 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.
