Question

The ratio of cars to trucks is 8 cars to 36 trucks. If there are 9 trucks, how many cars are there?

Answer 1

Answer: 2 Cars

Step-by-step explanation: 36 divided by 4 is 9 so you have to do 8 divided by 4 which is 2. 2 to 9 would be the ratio of cars to trucks.

Answer 2

Set up the proportion with the numbers on top equalling the cars and the numbers on the bottom representing the trucks.

`(8)/(36) = (c)/(9)`
c equals the number of unknown cars.
To solve the proportion, cross multiply (multiply 8 by 9 and 36 by c) and solve for c.
72 = 36c
Divide 36 from both sides to get the answer.
c = 2
If there are 9 trucks, there are 2 cars.
You can check this by dividing 2 by 9, and dividing 8 by 36. Since they both equal the same number, this answer is correct.

Hope this helps =)
