lets see here...
20 out of 50 like pizza.. how many would like pizza out of 450...
Ok lets solve this ...

20/50
is what you start off with as of right now.. Now lets divide from 450 to see how much times 50 goes into it!
450 Divided by 50=n
Since we don't know, we can make the multiplier n.
So far it is:
(20xN)/ 450
Now lets see..
___9
50)450
so that means the multiplier is 9..
~~~~~~~~~
(20x9) / 450
Now lets figure it out!!
20x9=180... so that means..

out of 450, 180 students would like pizza most likely.
