What is 79.45333... as a Fraction?

79.453 equals 595975 as a fraction.

How do you turn 79.453 repeating into a fraction?

Detailed Answer:

Step 1: To convert 79.453 repeating into a fraction, begin writing this simple equation:

n = 79.453 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (45). Multiply both sides by 10³ = 1000.

1000 × n = 79453.3 (equation 2)

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

1000 × n = 79453.3
 100 × n = 79.453
 900 × n = 71508

71508900 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 12 (the GCF - greatest common factor).

n = 71508900 = 71508 ÷ 12900 ÷ 12 = 595975. So,

79.453 = 595975 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 595975 is also equal to 793475 when expressed as a mixed number.

The repeating decimal 79.453 (vinculum notation) has a repeated block length of 1. It is also represented as 79.45333... (ellipsis notation) which equals approximately 79.4533333 (decimal approximation)(*).

The recurring decimal 79.453 can be written as a ratio of two integers having 5959 as the numerator and 75 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.
