Which fraction is a unit rate you can use to solve a ratio problem?
A. 3/4
B. 1/27
C. 27/1
D. 7/5
C. 27/1
A unit rate is a fraction where the numerator represents one unit and the denominator represents the corresponding number of another unit. To solve a ratio problem, you need a fraction that represents one unit of the given ratio.
Out of the given options, the fraction that represents a unit rate is C. 27/1. The numerator 27 represents one unit, and the denominator 1 represents the corresponding number of another unit.
To determine which fraction is a unit rate to solve a ratio problem, we need to understand what a unit rate is. A unit rate is a ratio in which the second term is 1. It compares an amount to a single unit of measurement.
Let's go through each option to see which fraction fits this criteria.
A. 3/4: This fraction is not a unit rate because the second term is not 1.
B. 1/27: This fraction is a unit rate because the second term is 1.
C. 27/1: This fraction is not a unit rate because the first term is greater than 1.
D. 7/5: This fraction is not a unit rate because the second term is not 1.
Therefore, the fraction that is a unit rate and can be used to solve a ratio problem is option B: 1/27.
