50 percent * 21 =
(50 / 100) * 21 =
(50 * 21) / 100 =
1050 / 100 =
10.5
Now we have the answer: 50% of 21 = 10.5. Alternatively, we can express it as: 10.5 is equivalent to 50 percent of 21.
Mathematical Notation: 50% * 21 = (50 / 100) * 21 = (50 * 21) / 100 = 1050 / 100 = 10.5
Formula: X100 × Y
Let's use the example of "What is 50% of 21?" to understand the calculation:
= 50100 × 21 = 10.5
Check our "What is X Percent of Y" Calculator for more methods and formulasStep 1: Start with the given output value, which is 10.5.
Step 2: Use the variable 'x' to represent the unknown value.
Step 3: From Step 1, we know that 10.5 is equivalent to 100%.
Step 4: Similarly, we can determine that 'x' represents 50% 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:
21 / x = 100% / 50%
Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 21 = 50 / 100
⇒ x = 10.5
Therefore, we conclude that 50% of 21 is equal to 10.5.
