PLEASE HELP COMPARING RATIOS

8 minutes per customer in Restaurant One.

6 minutes per customer in Restaurant Two.

7 minutes per customer in Restaurant Three.

Restaurant Two had the fastest service.

Method:

I divided the time it took – for example – 48 divided by 6. I would do this because I wanted to find out each person took (6 people), and the amount of time it took for each person to get their food. I would use division for this problem because I am finding how much each person took out of the whole time.

Answer

The 3rd restaurant is the fastest

Step-by-step explanation:

I. Compare Time per Customers

When 1st restuarant = 48/6 = 9

2nd restuarant = 42/7 = 6

3rd restuarant = 63/9 = 7

Given if in 1 min, I can serve 20 customers = 1/20 = 0.05

in 1 min, He can serve 10 customers = 1/10 = 0.1

See the different? I can serve better than him.

So The answer is the 3rd restuarant.

Hope that help :D
