Veronica is buying cubed cheese from mr. sands deli. she asks for 1 3/4 pounds. when mr. sand places some cheese in a container and weighs it, the scale shows 1 1/4 pounds. the container weighs 1/16 pounds. how many more pounds of cheese would mr. sand need to add to the scale to get the amount that veronica asked for? explain how you solved the problem.

Amount of cubed cheeses that Veronica wants to buy =1 3/4 pounds

=7/8 pounds
Weight of the container in which Mr. Sand places the cube =1/16 pounds 
Weight of the cubed cheese and container together =1 1/4 pounds 
=5/4 pounds 
Then the amount of cubed cheese placed by Mr.Sands =(5/4-1/16) pounds
=(20-1)/16 pounds 
=19/16 pounds
So the quanity of more cheese that Mr.Sands need to add to the scale =(7/4-19/16)pounds
=(28-19)/16pounds 
From the above debuction we can easily conclude that Mr.Sand need to add 9/16pounds of cubed cheese to fullfil the order placed by Veronica
