Answer:
Tom ate 12.5% of a whole pan.
Explanation:
To find the fraction of a whole pan that Tom ate, we need to determine the fraction of lasagna that he consumed.
In this case, Tom started with 7/8 of a pan.
To find the fraction of a whole pan that Tom ate, we can calculate the difference between what he started with (7/8) and what he has left.
Since the whole pan represents 1, we can subtract the fraction he has left from 1 to find the fraction he ate:
1 - 7/8 = 8/8 - 7/8 = 1/8
Therefore, Tom ate 1/8 of a whole pan.
Alternatively, if we want to express the fraction he ate as a percentage, we can convert 1/8 to a decimal and then multiply by 100:
(1/8) * 100 = 12.5%
Thus,
Tom ate 12.5% of a whole pan.
