First, let's remember how we calculate a percentage:
If we call the number "x", 4% is calculated by dividing x by 100 and then multiplying by 4:
This can also be represented as follows:
Thus, 4% of a number is 4/100 of that number. We can still simplify this result as follows:
We divide 4 by 4 and get 1, and also divide 100 by 4 and get 25.
Answer: 4% of a number is 1/25 of that number.
