Solve Word Problems Involving Percentages

From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts.And, thanks to the Internet, it's easier than ever to follow in their footsteps.

So 13/20, or 13 over 20, could also be viewed as 13 divided 20, or 13 divided by 20.

And let's add a couple of zeroes, as many zeroes as we would need.

Or another way you could say is you shift the decimal point over two spots to the right. Now, there's another way you could have done it.

And if you want to write it as a percentage you essentially multiply this number by 100.You will be given two of the values, or at least enough information that you can figure two of them out.Then you'll need to pick a variable for the value you don't have, write an equation, and solve for that variable.The format displayed above, "(this number) is (some percent) of (that number)", always holds true for percents.In any given problem, you plug your known values into this equation, and then you solve for whatever is left.And we could say, hey, look, 20 goes into 13 zero times. Well, to go from 20 to a 100-- forget the denominator. So this would have been a faster way to do it, especially if you recognize it's pretty easy to go from 20 to 100. And just a reminder, percent literally means per hundred, 65 per hundred, 65%.After doing all 10 problems, students should be more comfortable doing these problems and have a clear understanding of how to solve them. Word problems tend to be even wordier than this one. A few examples of some word problems using this method are in the table below.With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll learn how to solve simple percent problems in basic arithmetic.Description: This packet helps students practice solving word problems involving percent mark ups and discounts. Each page also has a speed and accuracy guide, to help students see how fast and how accurately they should be doing these problems.
