The rate that is not equivalent to the others is "1 for $0.75".
How to find the rates?
To find the rates, you need to take the quotient between the price and the number of units, these rates, give the value of a single item in dollars.
Here, the four rates are:
- 1) $36/27 = $1.33...
- 2) $4/3 = $1.33...
- 3) $20/15 = $1.33...
- 4) $0.75/1 = $0.75
So we can see that the rate which is not equivalent to the others is the last one (the bottom right one).
