Grade 9 Greatest Common Factor Algebra
posted by Jab .
Joey is having a party during the Major
League Soccer championship game. In order to make sure his guests are happy, he ordered the following appetizers from a nearby restaurant.
15 egg rolls
3 10slice pizzas
120 chicken wings
30 cheese sticks
5. What is the greatest number of guests that Joey can have at the party so that each person (including Joey) gets the same amount of each appetizer with nothing left over?
 For this I did 15+30+120+30 = 195 and because their greatest common factor is 15 is divided 15/195. There will be 13 guests coming.
6. What will each guest have to eat?
 How do I figure this out?
7. At the last minute, Joey finds out that there will be a total of 25 guests at his party. What is the least amount of each appetizer Joey must order so that everyone gets the same amount of each appetizer with nothing left over?

Including Joey, there are 15 people at the party.
6.
15/15 = 1 egg roll
30/15 = 2 pieces of pizza
And so on.
7. I'm sure you can work this out. 
I truely cant figure 7 out.

He needs:
25 egg rolls
5 pizzas
25 wings
25 cheese sticks
