To find the number that 21 is 4% of, we can set up a proportion.
Let's assume the unknown number is represented by 'x'.
The proportion can be set up as:
21 / x = 4 / 100
To solve for 'x', we cross-multiply and then divide:
21 * 100 = 4 * x
2100 = 4x
Dividing both sides by 4:
x = 2100 / 4
Simplifying the division:
x = 525
Therefore, 21 is 4% of the number 525.
So your answer is 525.
