Question

A caterer prepares three times as many pizzas as she usually prepares for a large party.

Answer 1

Answer: There are  45 party guests who will be served pizzas.

Step-by-step explanation:

Since we have given that

Number of pizzas usually prepare by the caterer = 5

Part of pizza will eat by each party guest is given by

$\frac{1}{3}$

As we have given that a caterer prepares 3 times as many pizzas as she usually prepares for a large party,

So, it becomes

$\text{Number of pizzas prepare by carterer this time}=5\times 3=15$

Let the number of party guests be x

According to question, it becomes,

Number of party guests will get the pizza serve is given by

$\frac{1}{3}\times x=15\\\\x=15\times 3\\\\x=45$

Hence, there are  45 party guests who will be served pizzas.

Answer 2

3 x 5 pizzas = 15 pizzas
1/3 of pizzas  x  people  =  15 pizzas
people  = 15 pizzas / (1/3)  =  45
