Question

this is the question pls help me 4 friends evenly divided up an n-slice pizza. One of the friends, Harris, ate 1 fewer slice than he received. How many slices of pizza did Harris eat? Write your answer as an expression.

Answer 1

Answer:

(n/4 - 1) slices

Step-by-step explanation:

The pizza would be divided into n slices, which in turn would be split among 4 people:

       

   n slices

----------------- = (n/4) slices per person

  4 people          

Harris must have eaten (n/4 - 1) slices.

Answer 2

Answer:

$\frac{n}{4}-1$

Step-by-step explanation:

If we have a pizza that has $n$ slices and we want to split it between 4 friends, then each friend will get $\frac{n}{4}$ slices.

Now, Harris is one of those friends so he receives  $\frac{n}{4}$  slices, but he eats one less than he receives. Therefore, we subtract one from this expression to get our final answer of $\frac{n}{4}-1$.

Hope this helped!
