Correct Question:

It took Jed 5/3 of an hour to complete his math homework on Friday, 3/4 of an hour on Saturday, and 5/6 of an hour on Sunday. How many hours did he take to complete his homework altogether?​

Answer:

[tex]Total = 3\frac{1}{4}\ hours[/tex]

Step-by-step explanation:

Given

[tex]Friday= \frac{5}{3}[/tex]

[tex]Saturday = \frac{3}{4}[/tex]

[tex]Sunday = \frac{5}{6}[/tex]

Required

Determine the total time spent

Total time is calculated as follows:

[tex]Total = Friday + Saturday + Sunday[/tex]

[tex]Total = \frac{5}{3} + \frac{3}{4} + \frac{5}{6}[/tex]

[tex]Total = \frac{20 + 9 + 10}{12}[/tex]

[tex]Total = \frac{39}{12}[/tex]

Divide numerator and denominator by 3

[tex]Total = \frac{13}{4}[/tex]

[tex]Total = 3\frac{1}{4}\ hours[/tex]
