What is 22.24444... as a Fraction?

22.244 equals 100145 as a fraction.

How do you turn 22.244 repeating into a fraction?

Detailed Answer:

Step 1: To convert 22.244 repeating into a fraction, begin writing this simple equation:

n = 22.244 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (4) and 2 digits in the non-repeating part (24). Multiply both sides by 10³ = 1000.

1000 × n = 22244.4 (equation 2)

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

1000 × n = 22244.4
 100 × n = 22.244
 900 × n = 20020

20020900 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 20 (the GCF - greatest common factor).

n = 20020900 = 20020 ÷ 20900 ÷ 20 = 100145. So,

22.244 = 100145 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 100145 is also equal to 221145 when expressed as a mixed number.

The repeating decimal 22.244 (vinculum notation) has a repeated block length of 1. It is also represented as 22.24444... (ellipsis notation) which equals approximately 22.2444444 (decimal approximation)(*).

The recurring decimal 22.244 can be written as a ratio of two integers having 1001 as the numerator and 45 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.
