Which fraction is a unit rate you can use to solve a ratio problem
A: 3/4
B: 7/5
C: 27/1
D: 1/27
The correct answer is D: 1/27. In a unit rate, the numerator is always 1, and the denominator represents the quantity being measured. In this case, 1/27 can be used as a unit rate to solve a ratio problem.
To determine which fraction is a unit rate that can be used to solve a ratio problem, we need to identify the fraction that represents a quantity of 1 for every 1 of another quantity.
Among the given options, the fraction that represents such a unit rate is D: 1/27. This means that for every 1 unit of the first quantity, there is 1/27th of the second quantity.
To determine which fraction is a unit rate that can be used to solve a ratio problem, we need to understand what a unit rate is. A unit rate is a ratio in which the denominator is equal to 1. In other words, it compares two quantities and expresses the rate of one quantity per one unit of the other quantity.
Let's look at the given options:
A: 3/4 - This fraction does not have a denominator of 1, so it is not a unit rate.
B: 7/5 - Again, this fraction does not have a denominator of 1, so it is not a unit rate.
C: 27/1 - This fraction has a denominator of 1, making it a unit rate.
D: 1/27 - While this fraction has a numerator of 1, it has a denominator of 27, so it is not a unit rate.
Therefore, the correct answer is C: 27/1.
