We have a multiple-choice question, about which numbers are less than 2.2
To do this we will go through it number by the number
For 3.25
This number is greater than 2
For 1/4
1/4 is the same as 0.25, this number is less than 2
For -5/2
-5/2 Being a negative number this by the rule will always be less than a positive number, so it is less than 2
For -3.5
-3.5 Being a negative number this by the rule will always be less than a positive number, so it is less than 2
For 0.1
This number is less than 2
In conclusion, all numbers except 3.25, are less than 2.2
