Understanding the Problem

In this problem, we are given a percentage and a value, and we need to find the original number. The percentage given is 11%, and the value is 22. We need to find the number that 22 is 11% of.

Breaking Down the Problem

To solve this problem, we need to understand the concept of percentages. A percentage is a way of expressing a value as a fraction of 100. In this case, 11% is equal to 11/100. We can rewrite the problem as:

22 = (11/100) × x

where x is the original number.

Solving the Problem

To solve for x, we can multiply both sides of the equation by 100/11, which is the reciprocal of 11/100.

x = 22 × (100/11)

x = 22 × 9.09

x = 200

Conclusion

Therefore, 22 is 11% of 200.
