Does 80 percent of 72 equal 125?

No. Taking any percent < 100% of a number will always be a smaller number, because you are finding a part of that number. (Percents > 100% are more than the number, and 100% is the number itself. 200%, for example, is twice the number.)


How can you prove that a perfect number can never be a prime number?

In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.
