What is the difference of finite and infinite?

its 2 types of numbers

Finite numbers: have an end. they can be extremely long, but as long as they have an end at some point they are finite

Infinite numbers never end. 1/3 is infinite, because the 0,3333 continues forever without even reaching exactly 1/3. 1/4 is finite, because it is exactly 0,25. So basically infinite numbers can never be written down exactly (in a decimal way), no matter how much paper you use, whereas finite numbers can.
