Claire Hurst · Answer 1

The correct answer is third option 3 : 4

Step-by-step explanation:

It is given that, Jamaal has 20 models of planes and cars

Also he has three times as many cars as planes

Let 'x' be the number planes.

Then number of cars = 3x

Total number of models = x + 3x = 4x

To find the ratio of his cars to total models

cars : total models = 3x : 4x

= 3 : 4

Therefore the correct answer is third option 3 : 4
