The fraction that is a unit rate you can use to solve a ratio problem is:
Start Fraction 27 over 1 End Fraction
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 and how to calculate it.
A unit rate is a rate in which the denominator is 1. It represents the amount of one quantity per one unit of another quantity. To find the unit rate, divide the numerator by the denominator.
Let's go through each of the given options:
34: This is simply a whole number with no fraction, so it cannot be a unit rate.
Start Fraction 3 over 4 End Fraction: This fraction has a numerator of 3 and a denominator of 4. To check if it is a unit rate, we divide the numerator by the denominator.
3 ÷ 4 = 0.75
Since the denominator is 4, it is not a unit rate.
75: Similar to the first option, this is a whole number with no fraction, so it cannot be a unit rate.
Start Fraction 7 over 5 End Fraction: This fraction has a numerator of 7 and a denominator of 5. Let's calculate the unit rate by dividing the numerator by the denominator.
7 ÷ 5 = 1.4
Since the denominator is 5, it is not a unit rate.
271: This is another whole number with no fraction, so it cannot be a unit rate.
127: Similar to the previous options, this is a whole number with no fraction and cannot be a unit rate.
Therefore, none of the given options is a unit rate that can be used to solve a ratio problem.
