Question

Brian counted 15 red cars and 20 blue cars in the parking lot. If the number of red cars stays the same, how many more blue cars would need to be added so the ratio of red cars to blue cars is 1 to 2?

Answer 1

10 more blue cars for the ratio to be 1 to 2 because 15/15 is 1 and 30/15 is 2 so it 1 to 2
