There are 20 kids on a bus, 60% of them have blue backpacks. How many is this? The teacher shows how to solve a percentage word problem using proportion ratios.

Create a percent proportion using the given values in this word problem. Not sure how to set that up? Then watch this short video and see how the teacher sets up this percent proportion according to the given values.

So x amount of people were surveyed and 68 of them said algebra was their favorite subject. Set up a percent proportion to identify the number of people surveyed. That's often the hardest part, setting up the equation. So observe the...

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

In this word problem, the skill to remember is to match up the similar measurements. This means the inches match up with the inches and the feet match up with the feet measurements. This problem is a ratio and is written as fractions....

Use the knowledge of multiplying fractions to find a percent of a number. The video builds the process to find the percent of a number by recalling that the word of in fraction problems meant to multiply. Finding the percent of a...

Could anyone really eat 15 feet of a sub sandwich in one day? That's how much this math problem says he ate. He actually started out with a bigger sub sandwich. How big was it to start? The instructor uses a table to illustrate how you...

A word problem, chemistry, and percent? I know you want to throw your hands in the air and run away from this problem, but please don't. Pay close attention as the instructor helps you unpack this word problem to set up an equation that...

When you first read this word problem it seems pretty daunting. The instructor explains how to identify the variables, how to convert percentage to whole numbers, and how to set up the problem and solve it. She uses a Venn diagram as a...

First identify the parts of the word problem. Next identify the variable, decide what formula to use, figure out the quantities, insert the quantities into the equation, and now solve. There are many parts to solving this word problem so...

Does this word problem describe exponential growth? Is something increasing? Is it increasing at a constant rate? How much is it increasing? Use the function formula for exponential growth to figure out this problem.

Is there a formula to help find the total in a percent problem? Given the part and the percent, the resource shows how to find the total. The video provides a two-step formula to find the total and goes through two word problems to...

Converting percents to decimals, and the other way around, can be tricky. Sal shows young mathematicians how to simplify this process with two sample equations and one word problem.

Another word problem to figure out. Well, first off you are trying to figure out the percent of something and this means your formula will be a proportional equivalent. Once you have the known terms in the correct places you can figure...

This word problem on simple interest has a bit of a twist. When you read this word problem it boggles the mind. I know, it boggled mine. But never fear, the instructor takes you through this seemingly complicated interest problem...
