Answer:
you would eat 1/4 of the box to fit the remaining cereal.
Explanation:
If there is 3/4 of a cereal box remaining and you eat to fit the remaining cereal, the fraction of the box that you eat can be determined by subtracting the remaining fraction from 1.
To find the fraction of the box that you eat, subtract 3/4 from 1:
1 - 3/4 = 4/4 - 3/4 = 1/4
Therefore, you would eat 1/4 of the box to fit the remaining cereal.
