Thirty percent of $60 is $18. The mathematical equation used to solve this problem is: 0.30 x $60 = N. An alternative method is to multiply 30 by $60 and then divide the answer by 100. Thus, 30 x $60 = $1,800, and $1,800 / 100 = $18.
Percentage problems consist of three values: the base, the rate or percent, and the percentage or amount. The base is the quantity from which a percentage is taken. In the given equation, $60 is the base, while 30 is the rate or percent. The percentage or amount, which is what this particular example seeks to find, is $18.
Percentage problems are often useful in determining the final price of an item on clearance after a certain price deduction. For example if a dress originally costs $50 and is marked 30 percent off, the equation $50 x 0.30 = $15 lets the shopper know she can expect to pay $15 less than usual for the dress, or $35.
Learn MoreTwenty percent of 100 is 20. To calculate the percentage of a number, convert the percentage to a decimal number; move the decimal point two places to the left, and multiply by the number. The word percent means per 100.
Full Answer >Percent yield is simply the actual yield (the mass of resultant) divided by the theoretical yield (the most that can be attained). Therefore, the possibility of having a percent yield greater than 100 is impossible unless an error is made during the procedure.
Full Answer >A $35 item that is marked 40 percent off has a final cost of $21. The markdown is calculated on its own before it is subtracted from the original price to determine the final total.
Full Answer >When expressed as a fraction, 15 percent is equal to 15/100. This can be simplified further by dividing both the numerator and denominator by 5, resulting in 3/20.
