560 / 28 = 20....so the driver travels 20 miles per gallon
on 35 gallons......35 * 20 = 700 miles <==
or u can also do it this way...
560/28 = x / 35....560 miles to 28 gal = x miles to 35 gal cross multiply because this is a proportion (28)(x) = (560)(35) 28x = 19600 x = 19600/28 x = 700 miles <==
so u can either do it by finding the unit rate or by making a proportion. either way will result in the same answer.
