Important points of percentage
Percentages have no dimension. Hence it is called a dimensionless number.
If we say, 50% of a number, then it means 50 percent of its whole.
Percentages can also be represented in decimal or fraction form, such as 0.6%, 0.25%, etc.
To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.
Percentage formula = (Value/Total value) × 100.
1. What is 50% of 30?
Ø Given 50% of 30
Ø = (50/100)*30
Ø = 1500/100
Ø = 15
Ø Therefore, 50% of 30 is 15.
2. Find 20% of 40?
Ø Given 20% of 40
Ø = (20/100)*40
Ø = (20*40)/100
Ø = 800/100
Ø = 8
