To determine what a unit rate is, let's analyze each of the given options:
1. Option A: "a rate with one in the numerator"
- This option describes a situation where the numerator (the top number in a fraction) is one. For example, in the rate [tex]\(\frac{1}{2}\)[/tex], the numerator is one. While this is a form of a rate, it does not define a unit rate.
2. Option B: "a rate in which the numerator and the denominator are ed"
- This option appears to be unclear and potentially incomplete. It does not provide a coherent definition of a unit rate. Therefore, it cannot be considered the correct answer.
3. Option C: "a rate with one in the denominator"
- This option is the definition of a unit rate. A unit rate compares a quantity to one unit of another quantity. For instance, if you drive 60 miles in 1 hour, the unit rate is 60 miles per hour. The denominator in this case is 1 hour, making it a unit rate.
4. Option D: "a rate in which the denominator is greater tha"
- This option is incomplete and does not provide a clear definition. It seems to be cut off and doesn't convey the complete idea of a rate.
By carefully examining all the options, we conclude that the correct answer is:
Option C: "a rate with one in the denominator"
