Well my teacher said there were 3 ways for working them out, you wouldentmind going over me with them, help would be thanking =]

I know one way which is using mulitplication:

Example: 20% of 60

20/100 of 200/1 (i canecel with common factor then times top two..)

also theres this "find 1%" one and fidnign 10% method, explain that if possible

the other one I THINK its a division method but ime not 100% sure.

HELP IS VERY GREAT FULL THANKS!
