what is the smallest number that 22 can be divided by without getting a decimal?

-22       I guess

22/-22=-1

Very clever, Melody. I was going to answer a fraction or a decimal, but negative numbers are even smaller.

Actually i did not even think of fractions.  

You have a very good mind  for mathematics and logical thinking.   

Thank you, Melody.

At certain times I do... sometimes though, it's just about finding the fastest/easiest method for me.
