Find the amount of sap the maple syrup producer collected from each tree if the total amount (5 gallons) was redistributed equally among the trees.

The picture in the attached figure

we know that
total amount of sap =[3*(1/4)+2*(3/8)+4*(5/8)+1*(1)]
total amount of sap =[(3/4)+(6/8)+(20/8)+(1)]
total amount of sap =[(3/4)+(3/4)+(10/4)+(4/4)]
total amount of sap =[20/4]
total amount of sap =5 gallons
total of trees=10

[amount of sap collected from each tree]=total amount of sap/total of trees

[amount of sap collected from each tree]=5/10----> 0.5 gallons per tree

the answer is
0.5 gallons
