- 30% = 30 parts out of 100 parts
The Formula to Calculate Percentage
To find out what a certain percentage of a number is, we can use the following formula:
[ \text{Percentage Value} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Total Value} ]
In this case, the total value is 50, and we want to find out what 30% of 50 is.
Step-by-Step Calculation
Now, let's apply the formula to find 30% of 50.
-
Identify the Percentage and Total Value:
- Percentage = 30
- Total Value = 50
-
Insert the Values into the Formula:
[ \text{Percentage Value} = \left( \frac{30}{100} \right) \times 50 ]
-
Perform the Calculation:
- First, calculate (\frac{30}{100}): [ \frac{30}{100} = 0.3 ]
- Now, multiply this by 50: [ 0.3 \times 50 = 15 ]
Conclusion
So, 30% of 50 is 15! 🎉
