Final answer:
Rose and her roommates ate 5/6 of a pint of ice cream in total.
Step-by-step explanation:
To find out how many pints of ice cream Rose and her roommates ate in total, we need to add the amounts they consumed on Friday and Saturday night. On Friday, they ate 1/3 of a pint, and on Saturday, they ate 1/2 of a pint. To add these fractions, we need to find a common denominator, which in this case is 6. Converting 1/3 and 1/2 to sixths gives us 2/6 and 3/6 respectively. Adding these fractions together gives us 5/6. So, Rose and her roommates ate 5/6 of a pint of ice cream in total.
