Answer: 10

Step-by-step explanation:

 [tex](\frac{1}{2}+\frac{3}{4})[/tex]÷[tex]\frac{1}{8}[/tex]

= [tex](\frac{1}{2}(\frac{2}{2})+\frac{3}{4})[/tex]÷[tex]\frac{1}{8}[/tex]

= [tex](\frac{2}{4}+\frac{3}{4})[/tex]÷[tex]\frac{1}{8}[/tex]

= [tex](\frac{5}{4})[/tex]÷[tex]\frac{1}{8}[/tex]

= [tex](\frac{5}{4})[/tex]x[tex]\frac{8}{1}[/tex]

= [tex]\frac{40}{4}[/tex]

= 10
