Answer 2

Given: Luigi uses 39 cups of flour for every 6 pizzas he makes.

To find: The correct answers to the blanks in the table

Solution:

6 pizzas need 39 cups of flour.

Then, 1 pizza needs = 39/6 cups of flour.

Therefore, 4 pizzas need = 39/6 × 4 = 13/2 × 4 = 13 × 2 = 26 cups of flour.

39 cups of flour can make 6 pizzas.

Then, 1 cup of flour can make = 6/39 pizzas.

Therefore, 13 cups of flour can make = 6/39 × 13 = 6/3 = 2 pizzas.
