Answer:
2/3 gallons
Step-by-step explanation:
Given data
We have the following data
1/2 gallons is the same as 0.5 gallons
hence 0.5 gallons will cover 3/4 of his deck
x gallons will cover 1 of his deck
cross multiply we have
3/4*x = 0.5*1 gallons
3x/4= 0.5
3x= 2
divide both sides by 3
x= 2/3
Hence 2/3 gallons will cover the entire deck
