Here's where the second formula that we've discussed comes in multiply 65 by 0.01 which is 0.65 Let's see the first step is to find out the opposite of the discounted percent so let's take 100 percent minus 35 percent to get 65 percent. Sales are Great! Right? What if something with a hefty price tag of $250 catches your eye and it's on sale at 35 percent off.
So your final answer should be 315 books.Ġ.35 × 900 = 315 Books 03: Calculating Discounts Then we take 0.35 and multiply it by the number of books that make 100% which is 900. How many books will the school get?Īnswer: According to our formula we first need to multiply 35 by 0.01 which is 0.35 Task: There are 900 books in your local book store the store is going out of business and has decided to give 35% of their books to a nearby school. In the end, you're paying $4 a day in interest. Then you multiply the $100 that you borrowed which makes 100% in this case by 0.04. To solve this task you need to do two simple multiplications at first you have to multiply 4 by 0.01 which is 0.04 that's 4% in its decimal form. Just imagine if you borrowed $100 from a friend and he's going to charge you an interest rate of 4% a day so exactly how many dollars is this 4%=? Let's say you know the percentage of something but you don't know the numerical value. The puppies you're giving away would be 3 divided by 5 times 100 which is 60%.ģ / 5 × 100 = 67% 02: Working with the Given Percentage Divide 2/5 and multiply that number by 100 that gives us 40%. So, what percentage of your puppies will you keep and what percent will you give away?Īnswer: We'll start with the puppies you're going to keep. Task: Your dog just gave birth to the 5 cutest puppies. In the end, you'll get 25% and there you go, you consumed 25% of your mangos when you ate 2 of the 8.
So for our little task, it's 2/8 and then multiplies that number by 100. But since we're after the percent you'll need to multiply the result by 100% as well. To do that you just have to divide the number of mangos you ate which is 2 by the number of mangos that make 100 percent which is 8. You bought 8 mangos which make 100 percent that's your total inventory and you ate 2 mangos out of the 8.Īll you have to do is find out what percent of the total these 2 mangos make. What percent of your mangos have you eaten? Let's say for instance you bought 8 mangos and then ate up 2 down right away. Mathematically, it's a way to express a number as a part of a whole.
