Answer 1

8 7/20

Step-by-step explanation:

Time preparing the arena=2 1/4=2×4+1/4=9/4

in ticket office=2 1/2=2×2+1/2=5/2

during the gig=3 3/5=3×5+3/5=18/5

total work=9/4+5/2+18/5

To solve this we will have to find the LCM of their denominator

=L.C.M of 4,2,5=20

9/4=9/4×5/5=45/20

5/2=5/2×10/10=50/20

18/5=18/5×4/4=72/20

=45/20+50/20+72/20=167/20

167/20=8 7/20
