Start Fraction 1 over 27 End Fraction
The fraction that is a unit rate to solve a ratio problem is Start Fraction 1 over 27 End Fraction.
To identify the fraction that represents a unit rate, you need to understand that a unit rate is a rate that compares a quantity to one unit of another quantity. In a ratio problem, the unit rate is the ratio of one quantity to one unit of another quantity.
Looking at the given options:
1. Start Fraction 7 over 5 End Fraction
2. Start Fraction 1 over 27 End Fraction
3. Start Fraction 3 over 4 End Fraction
4. Start Fraction 2 over 71 End Fraction
Out of these options, the fraction that represents a unit rate is Start Fraction 3 over 4 End Fraction (Option 3). This fraction compares 3 to a unit of 4.
Therefore, Start Fraction 3 over 4 End Fraction is the correct answer.
