For this case what we should do is find the total weight of the food.
We have then:
There are 3 different cheeses. Yasuko buys 3/4 of a pound of each:
\((3) (\frac {3} {4}) = \frac {9} {4} = 2 \frac {1} {4}\)
There are also 4 different meats. She buys 1/2 of a pound of each:
\((4) (\frac {1} {2}) = 2\)
Then, the total sum is given by:
\(2 \frac {1} {4} + 2 = 4 \frac {1} {4}\)
Answer:
The total food that yasuko did buy at the deli was:
\(4 \frac {1} {4} pounds\)
