Direct and Indirect proportion

This mathematics lesson for Grades 7, 8 and 9 will help you to understand direct and indirect proportion – two topics that can sometimes be quite tricky. It is important to know that direct proportion has a constant ratio between the x and y value and that the product of the x and y value of the indirect proportion on the other hand is constant. It will just make life easier for you. Also remember, like the example that you will encounter in the video: if there are more people to paint a house, the paint job will be done quicker.
