Final answer:
Dan's sister ate 1/4 pound of strawberries which is found by multiplying 3/4 pound by 1/3 and simplifying the resulting fraction.
Step-by-step explanation:
To find out how many pounds of strawberries Dan's sister ate, we need to calculate 1/3 of the 3/4 pound of strawberries Dan picked. This is a multiplication of fractions problem.
First, we multiply the two fractions:
(3/4) * (1/3) =
(3 * 1) / (4 * 3) = 3 / 12.
After simplifying the fraction, we get:
3 / 12 = 1/4
So, Dan's sister ate 1/4 pound of strawberries.
