Answer 1

The first number is 80% of the second number, not 75%, hence, Brad is wrong.

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, a second number is 125% of the first number.

Let the first number be 100, then the second number will be:

125% of 100

= (125/100) × 100

= 125

Now, divide the first number, 100, by the second number, 125, and then multiply with 100 to know how much % the first number is of the second number:
(100/125) ×100%

=80%

Therefore, the first number is 80% of the second number, not 75%.

Hence, Brad is wrong.
