Final answer:
The question regarding how many doughnuts were left after Janice bought 2 dozens of 2/3 is unclear and seems to contain a typo. The quantity of doughnuts cannot be determined without additional context or clarification.
Step-by-step explanation:
The question seems to contain a typo or error. Assuming Janice bought '2 dozens of doughnuts' at ⅓ (2/3) each and wants to know how many are left, we can proceed to calculate the total number of doughnuts first. A dozen is 12 items, so two dozens would be 2 × 12 = 24 doughnuts. However, if Janice bought them at a rate of 2/3 per doughnut, the calculation does not make clear sense, as 2/3 refers to a fraction of a single doughnut, not a quantity that can be multiplied by dozens directly.
Perhaps the question intended to ask how many doughnuts are left after Janice gave away or consumed 2/3 of them. But without the initial total or the exact context, the question cannot be answered accurately.
