Drag and drop each expression into the correct boxes to complete the explanation. The expression that represents how many guests the pizzas can serve is . How many party guests will the pizzas serve? Drag and drop the number of guests into the box. The pizzas can serve guests.

Answer 1

Total number of guests = 16

Solution:

Number of pizzas the caterer usually makes = 4

Number of pizzas the caterer make for a large party = twice of 4

                                                                                       = 2 × 4

                                                                                        = 8

So,the caterer makes 8 pizzas for a large party.

Quantity of pizza eat by each guest = $\frac{1}{2}$ of a pizza

Let the number of guests be taken as x.

Total guest in the party

           = Total number of pizzas ÷ Amount of pizza eat by each guest.

   ⇒ $x=8\div \frac{1}{2}$

Division changed into multiplication when the digit of the denominator is reversed.

   ⇒ $x=8\times \frac{2}{1}$

   ⇒ x = 16

Hence pizzas served for 16 guests.
