Question

a container at a deli has exactly 5 pounds of cheese slices.each cheese slice weughs excactly 2 ounces. how many total cheese slices are in the container?

Answer 1

5 pounds= 80 ounces
Since each piece weighs 2 ounces you divide 80 by 2 and get 40. 
So, there are 40 slices of cheese

Answer 2

Weight of one cheese slice = 2 ounce

Quantity of cheese slice in one container = 5 pounds.

Here we need to convert 1 pound into ounce first.

1 pound =16 ounce

So applying unitary method here,

Converting 5 pounds into ounces.

5 pounds of cheese = 5*15 = 80 ounces.

So Number of cheese slices = Amount of cheese slice in container divided by quantity of cheese in one slice

So number of cheese slices = 80 divided by 2 = 40

Answer : Number of cheese slices equals 40.
