Answer:

Frank spent [tex]\frac{3}{2}[/tex] hours times for studying as John.

Step-by-step explanation:

Given that,

John spent time in studying = [tex]3\frac{1}{4}[/tex] hours.

Frank spent time in studying = [tex]4\frac{7}{8}[/tex] hours.

To find:  Frank spent how many times the amount of hours studying as John?

So, Let the frank spent [tex]x[/tex] (in hours) times of hours studying as John.

According to Question,

time taken by Frank for studying = [tex]x\times[/tex] time taken by John for studying

                                                  [tex]4\frac{7}{8}=x\times 3\frac{1}{4}[/tex]

                                                  [tex]\frac{39}{8}=x\times \frac{13}{4}[/tex]

                                                   [tex]x=\frac{\frac{39}{8} }{\frac{13}{4} }=\frac{39}{8} \times\frac{4}{13}[/tex]      

                                                   [tex]x=\frac{3}{2}[/tex] hours.

Therefore, Frank spent [tex]\frac{3}{2}[/tex] hours times for studying as John.
