Question

Amir notices that 3 out of every 50 cars that pass by his window

are green. If he observes 400 cars, what is the best estimate for how
many of them will be green?

Answer 1

24 cars are green

Explanation:

We know

Amir notices that 3 out of every 50 cars that pass by his window are green.

So, the ratio is 3:47

To get from 50 to 400, we time 8.

If he observes 400 cars, what is the best estimate of how many will be green?

We take

3 x 8 = 24 cars are green

So, there will be 24 cars that are green.
