What is 94.17555... as a Fraction?

94.175 equals 42379450 as a fraction.

How do you turn 94.175 repeating into a fraction?

Detailed Answer:

Step 1: To convert 94.175 repeating into a fraction, begin writing this simple equation:

n = 94.175 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (5) and 2 digits in the non-repeating part (17). Multiply both sides by 10³ = 1000.

1000 × n = 94175.5 (equation 2)

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

1000 × n = 94175.5
 100 × n = 94.175
 900 × n = 84758

84758900 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 2 (the GCF - greatest common factor).

n = 84758900 = 84758 ÷ 2900 ÷ 2 = 42379450. So,

94.175 = 42379450 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 42379450 is also equal to 9479450 when expressed as a mixed number.

The repeating decimal 94.175 (vinculum notation) has a repeated block length of 1. It is also represented as 94.17555... (ellipsis notation) which equals approximately 94.1755555 (decimal approximation)(*).

The recurring decimal 94.175 can be written as a ratio of two integers having 42379 as the numerator and 450 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.
