This tutorial shows you how to take a words problem and turn it into a percent proportion.
Then see how to solve for the answer using the mean extremes property of proportions. Sometimes the hardest part of a word problem is figuring out how to turn the words into an equation you can solve.
Then, students encounter the concept of aspect ratio, which is simply the ratio of a rectangle's width to its height, and solve a variety of problems involving aspect ratio.
Next, students learn how rates can be used to convert measurement units.
Ingredients sometimes need to be mixed using ratios such as the ratio of water to cement mix when making cement. Then think of some ratios you've encountered before!
This is a bit of a tricky definition, so make sure to watch the tutorial!This tutorial shows you how to use a proportion to solve!Word problems allow you to see the real world uses of math!This tutorial let's you see the steps to take in order to do just that! John has 30 marbles, 18 of which are red and 12 of which are blue.In other words, you are permitted to make copies for the students/children you are teaching, but not for other teachers' usage. You will need Adobe Reader to view them, including if you use a Mac or Linux.You can try other PDF viewers, but they seem to either omit or mess up some of the images.Sometimes the hardest part of a word problem is figuring out how to turn the words into an equation you can solve. The idea of proportions is that a ratio can be written in many ways and still be equal to the same value.This tutorial let's you see the steps to take in order to turn a word problem involving a blueprint into a proportion. That's why proportions are actually equations with equal ratios.This tutorial provides a great real world application of math.You'll see how to use the scale from a blueprint of a house to help find the actual height of the house.
