Harris ate n/4 - 1 slices of pizza

Explanation:

Answer 2

Harrison ate
`(n-4)/(4)` slices of pizza.

Explanation

4 friends evenly divided up a
`n`-slice pizza.

So, the number of slices each friend received
`=(n)/(4)`

Now, Harrison ate 1 fewer slice than he received. As he received
`(n)/(4)` slices, so 1 fewer than
`(n)/(4)` means......

`(n)/(4)-1 \\ \\= (n-4)/(4)`

Thus, Harrison ate
`(n-4)/(4)` slices of pizza.
