proportion-word-problems-pre-algebra-lesson

I solve three word problems that have to do with equal ratios - therefore, a proportion is involved. However, I don't use a proportion to solve every problem. In the first problem, I use a table of equal ratios. In the second, I write a proportion and solve it by cross-multiplying. And I solve the last problem in two different ways - using proportional thinking and then also with a proportion.
