Answer:

The answer is 4) A unit rate always relates quantities with the same units.

Step-by-step explanation:

It cannot be 1 because a unit rate relates a quantity to 1. Hence the word unit which means single or undivided whole.

It cannot be 2 because you can indeed use unit rates to compare two rates. In fact we do all the time in math! Just like comparing fractions.

It cannot be 3 because the rate has to be equivalent to its unit rate or else its wrong.

Thus making it four!

Option D is not true about unit rates.

  • Unit rate is simply a rate that has the denominator as 1. For example, if we want to write the rate at which water is poured per sec. If the speed is 7 m/s, then we can say the rate is 7m per 1 second.

  • Option A; This statement is true because as seen in the speed rate earlier explained, unit rate relates a quantity to one because it only has its denominator as one.

  • Option B: Statement is true because unit rates of similar units are often compared with each other. For example if we want to know which person has a higher speed every second while running a race.

  • Option C: This statement is correct because like said in option B explanation above, unit rates must have same units otherwise, it is no longer a unit rate as different units could lead to different unit rates.

  • Option D: This statement is not correct because unit rates does not always relate quantities with same units.
