Answer 1

Answer: They would use 300 pickles for 100 hamburgers.

Step-by-step explanation:

Given: McDonald's use 9 pickles for 3 hamburgers

⇒Ratio of hamburger to pickles=3:9

⇒McDonald's use pickles for 1 hamburger.

Now Number of pickles for 100 hamburgers= 100×3=300

Therefore, They would use 300 pickles for 100 hamburgers.
