How to write an improper fraction as a mixed number or whole number?

1 answer:

8 0

See how many times the denominator goes into the numerator. For example, with 24/8, 8 goes into 24 three times, so 24/8 is 3. If I had 25/8, then it would be 3 1/8 because you have one left over after you divide the 8 into 25.

Step-by-step explanation:

So in order to get this answer you want to use the combination formula which is $\frac{n!}{(n-r)!r!}$

Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation

so your going to have something looking like this $\frac{8!}{(8-2)!2!}$ now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.
