zalisa [80]

Answer:

\frac{4}{3} quarts of ice cream

Step-by-step explanation:

Given

Number of friends = 8

Size of ice cream = 1/6 quarts

Required

Total ice cream served

Let n represent the number of friends, s represent the size of ice cream and t represents total ice cream served;

t is calculated as thus;

t = n * s

t = 8 * \frac{1}{6} quarts

t = \frac{8}{6} quarts

Divide numerator and denominator by 2

t = \frac{4}{3} quarts

Hence, she serves \frac{4}{3} quarts in total
