Problema Solution
Dao has 2 3/8 lbs of hamburger meat. He is making 1/4-lb hamburgers. Does Dao have enough meat to make 10 hamburgers? Explain.
Answer provided by our tutors
The amount of meat needed for 10 hamburgers is:
10*(1/4) = 5/2
The amount of meat that Dao has:
2 3/8 = (2*8 + 3)/8 = 19/8
We need to to compare 5/2 and 19/8.
5/2 = (5*5)(2*4) = 25/8 and 25/8 > 19/8
This means that 5/2 > 2 3/8 that is, Dao doesn't have enough meat.
