Eating a complete sheep is one job
Lion 4 hours
It does 1/ 4 of the job in 1 hour
Leopard 5 hours
It does 1/ 5 of thejob in 1 hour
Bear 6 hours
It does 1/6 of the job in 1hour

Together they will do 1/4+ 1/12+ 1/6
Together they will do 1/ 2 of the job in one hour
So they will take 2 hours
So they will take 2 hours to eat the sheep
