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.Know More
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.Learn more about Fractions & Percentages
Subtracting decimals involves writing the two decimals one below the other and making sure that the decimal points line up before subtracting in the normal manner. However, the larger decimal should be placed above the smaller one. Similarly, if the two decimals do not have the same length, then add zeroes before subtracting them.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.Full Answer >
A percentage can be solved by multiplying a given quantity by a percent. It should be noted, however, that the percent should first be divided by the numeral 100 before doing the multiplication.Full Answer >
