In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. It is represented by the symbol “%”. Percentages are used like fractions and decimals, as ways to describe parts of a whole. While learning percentcalculations, one should know that the whole is considered to be made up of a hundred equal parts.

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.

7th Grade Math Percents Examples

1.What is 50% of 30?

ØGiven 50% of 30

Ø= (50/100)*30

Ø= 1500/100

Ø= 15

ØTherefore, 50% of 30 is 15.

2.Find 20% of 40?

ØGiven 20% of 40

Ø= (20/100)*40

Ø= (20*40)/100

Ø= 800/100

Ø= 8
