Question

Identify each as a ratio that is either part-to-part, part-to-whole, a rate, or a unit rate.

25 bricks on each pallet
a) Part-to-part
b) Part-to-whole
c) Rate
d) Unit rate

Answer 1

The ratio '25 bricks on each pallet' is classified as a unit rate because it compares the number of bricks to one pallet.

Step-by-step explanation:

The phrase '25 bricks on each pallet' is describing a ratio related to bricks and pallets. To classify this ratio, we look at the context: it's describing how many bricks are present for one pallet. This is a comparison of two different types of measurements (one type of item per another type of item), indicating the number of bricks per one pallet, which makes it a unit rate.

It is not part-to-part, as we are not comparing two subsets of the same whole. Nor is it part-to-whole, as we're not comparing the bricks to the total number of bricks associated to all pallets. It's also not just a rate, which would typically be used for different units (like miles per hour). Here, we're dealing with a unit rate since it's defining the amount of a certain item (bricks) in respect to one unit of another item (pallet).
