To add a percentage to a number, change the percentage to a decimal value, and add one to the value. Multiply the number by the result.
Know MoreConvert a percentage to a decimal value by dividing it by 100 or moving the decimal to the left two places. For example, 19 percent equals 0.19.
Add one to the decimal number. For example, 0.19 + 1 = 1.19.
Multiply the number by one plus the decimal value. For example, 250 x 1.19 = 297.5. This result means that 19 percent of 250 added to 250 equals 297.5.
A percentage is subtracted from a number by calculating the percentage in relation to that number and then performing a basic subtraction function. For example, to calculate 200 minus 70 percent, a person must first know that 70 percent of 200 is 140. Then, 140 is subtracted from 200 to get the answer, which is 60.
Full Answer >To turn a number into its equivalent percentage, a person should move the decimal point two places to the right and then add the percent sign. For example, to turn the number 7 into a percentage, a person would move the decimal point two places to the right, which requires the addition of two 0s after the 7, and the percentage is expressed as 700 percent. In the case of .35, moving the decimal point two places to the right expresses the number in its percentage form as 35 percent.
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 >Add and subtract fractions by finding like denominators and then adding or subtracting the numerators. To multiply fractions, simply multiply the numerators and denominators together. To divide fractions, multiply the first fraction by the inverse of the second fraction. Finish by simplifying your answer.
