Final answer:
Tasha can eat granola for 11 days before she has to buy more.
Step-by-step explanation:
Tasha eats 1/3 of a cup of granola each day. She bought a box of granola containing 3 2/3 cups. To find out how many days she can eat granola before she has to buy more, we need to divide the total amount of granola by the amount she eats each day.
3 2/3 cups = (3 x 3) + 2/3 = 9/3 + 2/3 = 11/3 cups
Now, let's divide 11/3 by 1/3 to find out the number of days:
11/3 ÷ 1/3 = 11/3 x 3/1 = (11 x 3) / (3 x 1) = 33/3 = 11 days
Therefore, Tasha can eat granola for 11 days before she has to buy more.
