Answer:
24
Step-by-step explanation:
Given, 5:3 = 5 to 3
1. 40/5 (40 divided by 5) 8
(You would divide to know what to do next.
You would also divide by the 5 because the ratio of the cars are red to blue, and the question asks if there were 40 red cars, how many blue cars were there.)
2. Because 5 red cars grouped into 8 were 40, multiply 3 by 8.
3. 3 x 8 = 24.
Answer: 24.
