Answer: 25
Explanation:
To find the answer, we want to figure out how many times 1/3 goes into 8 1/3, so we use division.
convert 8 1/3 into an improper fraction
8 1/3 = (3 * 8 + 1)/3 = 25/3
we use 25/3 for the numerator and 1/3 for the denominator
so the number of hamburgers she can make is
(25/3) / (1/3)
= (25 / 3) * 3 the 3's cancel out
= 25 hamburgers
