Question

Each deli sandwhiches made uses 8/8 pound of roast beef.Marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left. How many del sandwhiches did she make

Answer 1

Marisa has made 6 sandwiches.

Explanation:

The pounds of roast beef required to make each sandwiches is
`(3)/(8)`, and not
`(8)/(8)` as erroneously typed in the question.

Given that each deli sandwiches made, uses
`(3)/(8)` pounds of roast beef.

Marisa started with 5 pounds, and had 2
`(3)/(4)` pounds left.

Thus,

pounds of roast beef used = 5 - 2
`(3)/(4)`

= 5 -
`(11)/(4)`

=
`(20 - 11)/(4)`

=
`(9)/(4)`

= 2
`(1)/(4)`

Marisa had used 2
`(1)/(4)` pounds of roast beef. So that;

the number of del sandwiches made = 2
`(1)/(4)` ÷
`(3)/(8)`

=
`(9)/(4)` ÷
`(3)/(8)`

= 6

Therefore, the number of sandwiches made by Marisa is 6.
