While ratios and proportions are often seen to be one and the same, there are many clear differences between the two. Proportions are used to find the quantity out of the total value of a population. For example, the proportion of girls in a certain grade level. Ratios on the other hand compare two values. In that same situation we might determine a ratio of boys to girls in a grade level. Another key different is that ratios are expressions and proportions are, by comparison, equation based.
The worksheets found below will introduce you to both proportions and ratios. We will also begin to help you make the connection to percentages and decimals with this in mind. We also have a section that will help you determine your own proportions.
