What is 104.0555... as a Fraction?

104.5 equals 187318 as a fraction.

How do you turn 104.5 repeating into a fraction?

Detailed Answer:

Step 1: To convert 104.5 repeating into a fraction, begin writing this simple equation:

n = 104.5 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (5), so multiply both sides by 10¹ = 10.

10 × n = 1045.5 (equation 2)

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

10 × n = 1045.5
 1 × n = 104.5
 9 × n = 941

n = 187318 (answer)

104.5 = 187318 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 187318 is also equal to 104118 when expressed as a mixed number.
