2.) a and b are two integers, and a>b. The sum of a and b is 5, but their product is less than 1. What can you say about a and b?

What I found is:

a is greater than b

a+b=5 , but when the multiply, it is less than 1

I dont know what to do next...i tried forming numbers that is valid for the description above..but failed..can anyone help me..
