a new parking lothas spaces for 450 cars. the ratio of spaces for fullsized cars to compact cars is 11 to 4. how many spaces are for fullsized cars? how many spaces for compact cars?

algebra 
Damon,
Say there are 11x big cars.
Then there are 4x small cars
11x+4x = 450
solve for x
Then you can get 4x easily.
