    Answer:

    Incorrect.

    Step-by-step explanation:

    Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be

    y = 1.25 x

    Or, y= 5/4x

    Now, multiplying it with 4/5, we get, x= 4/5y

    Or, x= 0.80 y

    But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That’s why Brad is incorrect.
