What is 6.22999... as a Fraction?

6.229 equals 623100 as a fraction.

How do you turn 6.229 repeating into a fraction?

Detailed Answer:

Step 1: To convert 6.229 repeating into a fraction, begin writing this simple equation:

n = 6.229 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (9) and 2 digits in the non-repeating part (22). Multiply both sides by 10³ = 1000.

1000 × n = 6229.9 (equation 2)

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

1000 × n = 6229.9
 100 × n = 6.229
 900 × n = 5607

5607900 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 9 (the GCF - greatest common factor).

n = 5607900 = 5607 ÷ 9900 ÷ 9 = 623100. So,

6.229 = 623100 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 623100 is also equal to 623100 when expressed as a mixed number.

The repeating decimal 6.229 (vinculum notation) has a repeated block length of 1. It is also represented as 6.22999... (ellipsis notation) which equals approximately 6.2299999 (decimal approximation)(*).

The recurring decimal 6.229 can be written as a ratio of two integers having 623 as the numerator and 100 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.
