What is 325.17333... as a Fraction?

325.173 equals 2438875 as a fraction.

How do you turn 325.173 repeating into a fraction?

Detailed Answer:

Step 1: To convert 325.173 repeating into a fraction, begin writing this simple equation:

n = 325.173 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (17). Multiply both sides by 10³ = 1000.

1000 × n = 325173.3 (equation 2)

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

1000 × n = 325173.3
 100 × n = 325.173
 900 × n = 292656

292656900 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 = 292656900 = 292656 ÷ 12900 ÷ 12 = 2438875. So,

325.173 = 2438875 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 2438875 is also equal to 3251375 when expressed as a mixed number.

The repeating decimal 325.173 (vinculum notation) has a repeated block length of 1. It is also represented as 325.17333... (ellipsis notation) which equals approximately 325.1733333 (decimal approximation)(*).

The recurring decimal 325.173 can be written as a ratio of two integers having 24388 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.
