Answer:
The expression that represents how many guests the pizzas can serve is 4 x 6 ÷ 1/4.
The pizzas can serve 96 guests.
Explanation:
For the first answer, it asks you an equation. As you can see, large parties are four times the amount of normal pizza, which is 6 pizzas, so the first part of the equation would be 4 x 6. In the second part of the problem, it states that each guest is estimated to eat 1/4 of a pizza, so you would do 4 x6 ÷ 1/4 since each guest will be eating 1/4 of a pizza at the party.
For the second part of the answers, the pizzas can serve 96 guests. All you have to do is take the equation and solve it. In this, 4 x 6 is being divided by 1/4. What you would do first is 4 x 6, which is 24, and this leaves you with 24 ÷ 1/4. As you should know, when you are dividing a number by a fraction, you flip the fraction and do multiplication instead, so in this case, it would now be 24 x 4. 24 x 4 is 96, which means that the pizzas can be served to 96 guests.
I also want to say, don't ever look at math as numbers. Just see it as something you can solve very easily if you take time into trying to solve it. Hope this helped a lot!
