London purchased 4 3/4 pints of ice cream for a party. If each guest will be served exactly 2/3 pint of ice cream, what is the greatest number of guests that London can serve?

7

Step-by-step explanation:

To solve this problem, we can use a rule of three.

The total amount of pints of ice cream is 4 3/4 = 4.75, and each guest will be served 2/3 pint of ice cream.

If one guest need 2/3 pint, X guests will need 4.75 pints:

1 guest -> 2/3 pint

X guests -> 4.75 pints

1/X - 2/3 / 4.75

X = 4.75 / 2/3 = 4.75 * 3 / 2 = 7.125

So the greatest number of guests that can be served is 7.
