Step-by-step explanation:
Work done by Clark in 1 day=60/9=6.6 units
Work done by Nelson in 1 day=60/15=4units
Total amount of work done in 1 day=4+6.6=10.6 units.
Amount of work done in 5 days=10.6×5=53 units
Amount of work left=60-53=7 units
Fraction of work left=Amount of work left/Total work=7/60
