- would 8/2 as a mixed number be 4 0/2 ?

and what is the difference of the mixed number of 2/8? I dont get it.(5 votes)- Only improper fraction will create a whole number or mixed number. An improper fraction will always have a numerator that is equal to or larger than the denominator.

8/2 is an improper fraction. 8/2 becomes just a whole number = 4. There is no fraction as 0/2=0.

2/8 is a proper fraction (the numerator is less than the denomintor). It can't be changed into a mixed number. All you can do is reduce it down to 1/4.

- How do you subtract fractions?(5 votes)
- There's a nice trick for subtracting fractions.

To find the numerator: cross-multiply numerators with denominators and subtract the products. Specifically, find (1st numerator * 2nd denominator) - (2nd numerator * first denominator).

To find the denominator: multiply the denominators.

Then reduce the answer as needed.

Example: Let's do 5/6 - 2/9.

The numerator is (5*9) - (2*6) = 45-12 = 33.

The denominator is 6*9 = 54.

So we get 33/54, which reduces to a final answer of**11/18**(from dividing top and bottom each by 3).
