Answer:

Step-by-step explanation:
First, convert the fractions into improper fractions, and make them have the same denominator.
First package: [tex]3\frac{3}{4} =\frac{15}{4}=\frac{30}{8}[/tex]
Second package: [tex]1\frac{1}{8} =\frac{9}{8}[/tex]
Third package: [tex]2\frac{1}{2}=\frac{5}{2}=\frac{20}{8}[/tex]
Notice that all the fractions have the same denominator, making it easy to add up. Now we add up the fractions.
[tex]\frac{30}{8}+\frac{9}{8}+\frac{20}{8}=\frac{59}{8} =7\frac{3}{8}[/tex]
