Jacob signs up to work for 2 1/2 hours at the school carnival. If each work shift is 3/4 hour, how many shifts will Jacob work?
mojhsa [17]

Answer:

3 complete shifts of 3/4 hour and 1 one-third of the 3/4 hour shift.

Step-by-step explanation:

Total work hours = 2.5 hours

Each shift = 0.75 hr

Number of shifts = Total work hours / Each shift

                             = 2.5 / 0.75

                             = 3.33

He worked for 3 complete shifts of 3/4 hour and

1 one-third of the 3/4 hour shift.
