They will each recieve [tex] 1\frac{1}{3} [/tex] slices each
Here's why: Since there are 8 slices and 6 of them we already know that they will get one slice each, so we can go ahead and subtract the 6 from 8.
That leaves us with 2 slices remaining. So, if they are going to evenly divide the two slices amongst the 6 of them, to find out how much they will receive in addition to the 1 slice already, you need to divide 2 by 6.
2÷6= [tex] \frac{1}{3} [/tex], so they will each receive the [tex] \frac{1}{3} [/tex] slice in addition to the 1 slice they already have.
So, you're answer would be [tex]1 \frac{1}{3} [/tex] slices of pizza per person
