Question

barbecue chicken pizza
ingredients:
5/8 cup grilled chicken
2/3 cup onions
1/4 cup mushrooms
1/2 cup green peppers
1/3 cup pineapple
1 cup barbecue sauce
5 1/3 cups cheese
1 pizza crust
write your answer as a fraction or as a whole or mixed number.
_____ cups

Explanation:

Step1: Identify the quantity of onions for one recipe

The recipe calls for $\frac{2}{3}$ cup of onions for one pizza.

Step2: Calculate the quantity for a double recipe

To find the quantity for a double recipe, we multiply the quantity for one recipe by 2. So we calculate $2\times\frac{2}{3}$.

Using the rule of multiplying a whole number by a fraction: $2\times\frac{2}{3}=\frac{2\times2}{3}=\frac{4}{3}$.

We can convert $\frac{4}{3}$ to a mixed number, which is $1\frac{1}{3}$.

Answer:

$\frac{4}{3}$ (or $1\frac{1}{3}$) cups
