When you multiply something (x) by a proper fraction ( less than 1 ), you always get something less than x, or the original number, because you're taking part of x and a part can't be larger than the whole.
Here's an example :
5 * 1/5 = 1
1<5
When you start with something that's less than 1 ( and positive), and you multiply it by a fraction, you get part of that positive fraction, so it will never be greater than 1.
Hope this helps!
I'm sorry if this is confusing ... it's too late for my brain to work at max level.
