What is 350.173... as a Fraction?

350.173 equals 2626375 as a fraction.

How do you turn 350.173 repeating into a fraction?

Detailed Answer:

Step 1: To convert 350.173 repeating into a fraction, begin writing this simple equation:

n = 350.173 (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 = 350173.3 (equation 2)

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

1000 × n = 350173.3
 100 × n = 350.173
 900 × n = 315156

315156900 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 = 315156900 = 315156 ÷ 12900 ÷ 12 = 2626375. So,

350.173 = 2626375 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 2626375 is also equal to 3501375 when expressed as a mixed number.

The repeating decimal 350.173 (vinculum notation) has a repeated block length of 1. It is also represented as 350.17333... (ellipsis notation) which equals approximately 350.1733333 (decimal approximation)(*).

The recurring decimal 350.173 can be written as a ratio of two integers having 26263 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.
