Answer:

[tex]5\frac{1}{8}[/tex] hours

Step-by-step explanation:

First find the common denominator for all numbers.

The common denominator for all of those numbers will be 8.

[tex]1\frac{3}{4}=1\frac{6}{8}[/tex]

[tex]\frac{3}{2}[/tex]         The fraction is improper so we must simplify it!

[tex]1\frac{1}{2}[/tex]       Then convert it to a mixed number having a common denominator of 8!

[tex]1\frac{1}{2} =1\frac{4}{8}[/tex]  

Final Results: [tex]1\frac{6}{8} + 1\frac{4}{8} +1\frac{7}{8} =5\frac{1}{8}[/tex]

Final Answer: [tex]5\frac{1}{8}[/tex]
