We are given some numbers and asked to find the greatest. We can see that all of them have a dot '.', which represents the decimal point.
To find the greatest number, we will first forget about the numbers that are on the right of the decimal point. We would get the list
A. 3
B 0
C 32
D 0
Out of this list, we find the greatest number, which is 32. That means that the number that is option C (32.5) is the greatest of the original list. That means option C is the correct answer
