What is 322.1433... as a Fraction?

322.143 equals 96643300 as a fraction.

How do you turn 322.143 repeating into a fraction?

Detailed Answer:

Step 1: To convert 322.143 repeating into a fraction, begin writing this simple equation:

n = 322.143 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (14). Multiply both sides by 10³ = 1000.

1000 × n = 322143.3 (equation 2)

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

1000 × n = 322143.3
 100 × n = 322.143
 900 × n = 289929

289929900 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 3 (the GCF - greatest common factor).

n = 289929900 = 289929 ÷ 3900 ÷ 3 = 96643300. So,

322.143 = 96643300 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 96643300 is also equal to 32243300 when expressed as a mixed number.

The repeating decimal 322.143 (vinculum notation) has a repeated block length of 1. It is also represented as 322.14333... (ellipsis notation) which equals approximately 322.1433333 (decimal approximation)(*).

The recurring decimal 322.143 can be written as a ratio of two integers having 96643 as the numerator and 300 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.
