Calculating the Percentage
To calculate the percentage of 9 out of 45, divide 9 by 45 and then multiply by 100. This gives us a result of 20%. So, we can say that 9 is 20% of 45.
The formula for calculating a percentage is: part/whole x 100. In this case, the part is 9 and the whole is 45. We divide 9 by 45 to get 0.2. Then, we multiply 0.2 by 100 to get 20%.
It is important to remember that when calculating percentages, it is necessary to use the same units for both the part and whole. Otherwise, you may end up with an incorrect answer. For example, if you were to compare 9 apples to 45 oranges, you would not get the same result as if you compared 9 apples to 45 apples.
Percentages are useful for comparing parts of a whole or for showing how much of something has been completed. Knowing how to calculate percentages quickly can help you make smarter decisions in your everyday life as well as in business settings.
