If 30% of 400 equals x, what is x?

Explanation:
Finding a percentage of a number means multiplying the number by that percentage written as a decimal. So 30% is 0.30, and 0.30 × 400 equals 120. Therefore x is 120. For context, 100 is a quarter of 400 (25%), 180 is 45% of 400, and 200 is 50% of 400, illustrating how different percentages give different results.
