For the measurement of 3/4 cup, which would be an incorrect combination?

To determine the correct answer, it is essential to analyze how each combination contributes to the total of 3/4 cup.

In option D, combining 2/4 cup with another 2/4 cup equals 4/4 cup, which is equivalent to 1 cup. This exceeds the required measurement of 3/4 cup, making it an incorrect combination for achieving that measurement.

On the other hand, options A, B, and C correctly provide measurements that equal 3/4 cup:

• In option A, adding 1/2 cup (2/4) to 1/4 cup directly gives 3/4 cup, which is correct.

• Option B involves adding 3/4 cup to 0 cups, resulting in the same 3/4 cup, validating this combination.

• Likewise, option C subtracts 1/4 cup from 1 cup, which gives 3/4 cup, confirming that this combination is also accurate.

Thus, option D is indeed the only combination that does not correctly measure out to 3/4 cup.
