Hi CH,
:
A car uses 10 gallons of gas on a trip of 280 miles. At that rate, how much gas will a trip of 476 miles require?
:
Let unknown gallons =x and set up a proportion of gallons/miles=gallons/miles:
10gal%2F280mi=x%2F476mi
%28476mi%29%2810gal%29%2F280mi=%28476mi%29x%2F476mi

476%2A10gal%2F280=x
%284760%2F280%29gal=x
17gal=x
highlight%28x=17gal%29
Happy Calculating!!!
