5 16 10 8. For example if total cost t is proportional to the number n of items purchased at a constant price p the relationship between the total cost and the number of items can be expressed as t pn. The ratio of hamsters to all class pets is the same as the ratio.

Proportions can tell us if two ratios are equal or not. Ratios Proportional Relationships. Compute unit rates associated with ratios of fractions including ratios of lengths areas and other quantities measured in like or different units.

One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same your ratios are proportional. Ratios and Proportional RelationshipsRatios and Proportional Relationships.

Two quantities are said to have a proportional relationship if they vary in such a way that one of the quantities is a constant multiple of the other or equivalently if they have a constant ratio. For example if total cost t is proportional to the number n of items purchased at a constant price p the relationship between the total cost and the number of items can be expressed as t pn.
