I've helped you with your last two problems. Now it's your turn.
I'll be glad to check your answer. 
5:9

Right.

The ratio of cars to trucks in the parking lot is five to seven. If there are 20 more trucks in the parking lot:
How many cars are there in the lot?
How many trucks are in the lot?
How many cars and trucks are there in the lot total? 
a parking lot has motorcycles and cars the number of motorcycles is 9 less than math question twice the number of cars if there are 46 wheels amongst all vehicles determine how many vehicles are in the parking lot
