What is 3.18444444... as a Fraction?

3.184 equals 1433450 as a fraction.

How do you turn 3.184 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.184 repeating into a fraction, begin writing this simple equation:

n = 3.184 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (4) and 2 digits in the non-repeating part (18). Multiply both sides by 10³ = 1000.

1000 × n = 3184.4 (equation 2)

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

1000 × n = 3184.4
 100 × n = 3.184
 900 × n = 2866

2866900 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 = 2866900 = 2866 ÷ 2900 ÷ 2 = 1433450. So,

3.184 = 1433450 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 1433450 is also equal to 383450 when expressed as a mixed number.

The repeating decimal 3.184 (vinculum notation) has a repeated block length of 1. It is also represented as 3.18444... (ellipsis notation) which equals approximately 3.1844444 (decimal approximation)(*).

The recurring decimal 3.184 can be written as a ratio of two integers having 1433 as the numerator and 450 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.
