Proportions are used to solve many real-life problems. As a matter of fact, there are a lot of problems we do daily that use proportions: converting units, using various rates, etc. To solve a problem that requires using proportion, we usually follow this process: 1. Assign a variable...
-treatment design to determine the functional relation between the use of varied technology-based interventions (i.e., a virtual manipulative [VM], a technology-based graphic organizer [TBGO], and a combination of both [VM TBGO]) and student accuracy in solving proportion word problems. ...
I will define "g" to stand for the amount of gravel that I need, and I will set up and solve my proportion: Keeping the context in mind, the answer to my equation is "g = 6", but the answer to this part of the exercise is that I need "six cubic feet of gravel". Then my ...

Once you've solved a few proportions, you'll likely then move into word problems where you'll first have to invent the proportion, extracting it from the word problem, before solving it.If twelve inches correspond to 30.48 centimeters, how many centimeters are there in thirty inches?I will ...
