    Answer: Smaller

    Step-by-step explanation:

    Multiplying a number by 1.25 increases it by a quarter

    Multiplying a number by 0.75 decreases it by a quarter

    1.25 / 0.75 = 0.9375

    Thus, increasing something by a quarter then decreasing it by a quarter, you are effectively multiplying that number by 0.9375, which is less than 1, so the number will decrease.
