This method is based on the fact that a percentage is a fraction of 100.
That is, if we need to calculate 80% of the number 400, we can represent it as 80/100, which is equal to 0.8.
Then we multiply 400 by 0.8 to get the answer.
Example: Calculate 80% of 400.
Solution: 400 x (80 / 100) = 320
This method is also based on the fact that a percentage is a fraction of 100.
However, instead of multiplying the number by a percentage, we divide the number by 100 and then multiply the result by a percentage.
Example: Calculate 80% of 400.
Solution: (400 / 100) x 80 = 320
This method is based on the fact that a percentage is a fraction of 100.
