Calculation:
1 gallon will cover:
=84(2)
=168 sq.feet
Let the total number of gallons of paint be x.
The proportion can be written as:
1168=x932
The ratios can be simplified further by doing cross product:
1168=x932
168(x)=1(932)
168x=932
168x168=932168
x=5.55 gallons

932168=x
Reduce the fraction 932168 to lowest terms by extracting and canceling out 4.
