Q: A: ### Quick Answer

**To subtract a percentage, one starts by converting the percentage into its decimal equivalent and subtracting the result from one.** Multiplying the answer by the original figure gives the value after subtracting the percentage. For instance, to subtract a tax of 27 percent from base pay, one coverts the percentage to 0.27 or (27/100). Basic pay x (1 - 0.27) gives the pay after the tax deduction.

Alternatively, an employee may first calculate the actual tax (basic pay x 27/100) and then subtract it from the basic pay. If a buyer pays $7.61 for an item that was priced at $6.95, the applicable percentage sales tax (x) is calculated as follows: x = (7.61- 6.95)/ 6.95; x = 9.5 percent.

Mathematically, a percentage of any value means the value multiplied by the percentage in its decimal form. For example, 35 percent of 80 means 0.35 x 80. It’s also possible to calculate a percentage rate of a value if the actual fraction is known. For example, if x represents a percent of 20 that equals 30, the percent is calculated as follows: x = 100 x 30/20. One multiplies the rate by 100 to convert from the decimal to percentage form.

A:

Full Answer >**Two-fifths is equivalent to 40 percent.**Dividing the numerator, 2, by the denominator, 5, yields a decimal value of 0.40. Decimal values can be converted to percentages by multiplying by 100, which means that 0.40 is equal to 40 percent.Filed Under: - Q:
## How do you do percentages in math?

A:Percent means “for every 100” or “out of 100.” If 80 percent of the population owns a computer, this implies that 80 out of every 100 people have one. The symbol “%” means percent. Writing a percentage therefore means representing the number out of 100. For instance, finding what percent of 20 is 40: (40/20) * 100 = 200%
