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!
