Formula: X100 × Y
Let's use the example of "What is 21% of 400?" to understand the calculation:
= 21100 × 400 = 84
Check our "What is X Percent of Y" Calculator for more methods and formulasStep 1: Start with the given output value, which is 84.
Step 2: Use the variable 'x' to represent the unknown value.
Step 3: From Step 1, we know that 84 is equivalent to 100%.
Step 4: Similarly, we can determine that 'x' represents 21% of the value.
Step 5: This leads us to two simple equations:
Step 6: To solve for 'x', we divide equation 1 by equation 2, considering that both equations have the same unit (%). Thus, we obtain:
400 / x = 100% / 21%
Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 400 = 21 / 100
⇒ x = 84
Therefore, we conclude that 21% of 400 is equal to 84.
