Answer:
6 fewer pizzas
Explanation:
The small cafe offers 6 fewer types of pizza than a restaurant. The restaurant offers 18 different types of pizzas and the cafe offers 1/3 as many types of pizzas which means what we have to find 1/3 of 18.
1/3 of 18 is 6 because 6*3 is 18
18 - 6 = 12 which is the number of pizzas the cafe offers but this is slightly irrelevant to the question because the question is asking how many FEWER pizzas the cafe sells than the restaurant
So, the small cafe offers 6 FEWER pizzas than the restaurant.
Hope this helps!
