Final answer:
To make one pizza, 1/10 cup of flour is required. For a dozen pizzas, you need to multiply the flour needed for one pizza by 12, resulting in 1.2 cups of flour.
Step-by-step explanation:
To make 5 pizzas, 1/2 cup of flour is used.
a. Flour needed to make one pizza
We divide the total amount of flour used by the number of pizzas to find out how much is needed for one. So, it would be 1/2 cup divided by 5:
1/2 cup ÷ 5 = 1/10 cup
Therefore, to make one pizza, 1/10 cup of flour is needed.
b. Cups of flour needed to make 1 dozen pizzas
One dozen pizzas is equivalent to 12 pizzas. To find out the total amount of flour needed, we multiply the amount of flour needed for one pizza by 12:
1/10 cup × 12 = 1 1/5 cups or 1.2 cups
Therefore, to make 1 dozen pizzas (12 pizzas), 1.2 cups of flour are needed.
