The primary purpose of this task is to represent ratios of two or more quantities with parallel tape diagrams. Note that the solution to this task assumes that students have already studied equivalent ratios and understand that when you have a context with 8 units of one quantity and 2 units of another quantity, you can say the ratio is 4:1 because it is an equivalent ratio. In general, when people talk about two ratios being the same, they really mean they are equivalent. Parallel tape diagrams might look a bit strange to the eye at first because, for example, the rectangle representing one teaspoon is larger than the rectangle representing one cup.
