2. nyoko is having a pizza party. two large pizzas serve 9 people. how many large pizzas should she order to serve 36 guests at the party? (example 1)
Answer
Explanation:
Step1: Find the number of people per pizza
Since 2 large pizzas serve 9 people, the number of people per pizza is $\frac{9}{2}$ people per pizza.
Step2: Calculate the number of pizzas needed
To serve 36 guests, we divide the total number of guests by the number of people per pizza. So the number of pizzas $n=\frac{36}{\frac{9}{2}}$. Using the rule of dividing by a fraction ($a\div\frac{b}{c}=a\times\frac{c}{b}$), we have $n = 36\times\frac{2}{9}$. $36\div9 = 4$, and $4\times2=8$.
