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.
Know MorePercentage 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 more about Fractions & PercentagesFor one to figure out their class grade percentage, they need to plug their individual grades into the formula that the teacher is using to determine their final grade. In most classes, different elements are worth a stated percentage of the whole grade. For instance, the midterm exam could be worth 20 percent, the final exam worth 20 percent, the assignments worth 50 percent, and class participation worth 10 percent.
Full Answer >The multiplication of percentages is accomplished by converting the percentage to decimals, and multiplying the decimals. To convert a percentage to a decimal, the percent sign must be removed, and the number divided by 100. The decimal point should always be moved two places to the left when dividing by 100. After dividing 75 by 100, the answer is 0.75.
Full Answer >The integer 25 can be expressed as an infinite number of equivalent fractions of the form 25a/a, where a is any integer. For example, 25 can be expressed as the fractions 50/2 (a=2), 75/3 (a=3), or 250/10 (a=10).
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.
