Answer :
Final answer:
Option 3, which is the ratio 4/1, represents a unit rate because it compares two measurements and has the value 1 in the denominator.
Explanation:
The question asks which ratio represents a unit rate. A unit rate is defined as a comparison of two measurements where one of the quantities is 1. The options are given as ratios and one must determine which of these ratios has 1 as either the numerator or the denominator to be a unit rate.
Looking at the options:
- Option 1: 12/2, which simplifies to 6/1, is not a unit rate since the second number is not 1.
- Option 2: 60/3, which simplifies to 20/1, is not a unit rate since the second number is not 1.
- Option 3: 4/1, which is already given as a unit rate since the second number is 1.
- Option 4: 4/3, which is a ratio where neither number is 1 and therefore is not a unit rate.
Therefore, the correct choice is Option 3: 4/1, as this represents a unit rate where one of the measurements has a value of 1.
