Question

Angela has 3 pounds of ground beef in her fridge raider. She uses 3/4 of the of a pound how much ground beef that should have left

Answer 1

if she used 3/4 of a pound, then

3 minus 3/4 = 2 1/4 pounds left

but if the question is actually asking what's left after using 3/4 of the 3 pounds then she has 1/4 of 3 pounds left which is 1/4 x 3 = 3/4 pound left

"3/4 of the of a pound" is not correct grammar, and might indicate the problem was not copied accurately. There's a possible ambiguity in what's being asked.
