Which fraction is a unit rate you can use to solve a ratio problem
1: 3/4
2:1/27
3: 7/5
4: 27/1
The unit rate that can be used to solve a ratio problem is 4: 27/1.
A unit rate is a ratio that compares a quantity to one unit of another quantity. In this case, we want to find a fraction that represents a unit rate.
Looking at the options, the fraction that can be used as a unit rate is:
4: 27/1
This is because the fraction 27/1 represents the ratio of 27 units of one quantity to 1 unit of another quantity, making it a unit rate.
To determine which fraction is a unit rate that can be used to solve a ratio problem, we need to find the fraction where the denominator represents a single unit.
In a ratio problem, the units being compared should be the same. In the given options, we can see that option 4, 27/1, represents the ratio where the denominator (1) represents a single unit. This means that for every 27 units of one thing, there is 1 unit of another thing, making it a unit rate.
Therefore, the correct answer is option 4: 27/1.
