Is 5 divisble why?

Answer 1

The word is "divisible", not "divisble". And you can't just say that one number is "divisible". You can say that one number is, or is not, divisible by a second number - meaning that when you divide, you get no remainder (if you divide on a calculator, you'll get a whole number, without decimals).
