Answer:

He needs 3.75 lbs of sugar and 1.25 lbs of water.

Explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 75%

Write a proportion:


(5)/(x)=(100)/(75)

Cross multiply:


100x=5\cdot 75\\ \\100x=375\\ \\x=(375)/(100)=3.75

So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.
