Formula: X100 × Y
Let's use the example of "What is 90% of 80?" to understand the calculation:
= 90100 × 80 = 72
Check our "What is X Percent of Y" Calculator for more methods and formulasStep 1: Start with the given output value, which is 72.
Step 2: Use the variable 'x' to represent the unknown value.
Step 3: From Step 1, we know that 72 is equivalent to 100%.
Step 4: Similarly, we can determine that 'x' represents 90% 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:
80 / x = 100% / 90%
Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 80 = 90 / 100
⇒ x = 72
Therefore, we conclude that 90% of 80 is equal to 72.
