Maths % Question

[JustAProg]

OK I can find the percentage of a number against another:
Lets say A=45 and B=90

Label1.text = A * 100 \ B

The answer would be 50, as 45 is 50% of 90

How do I go the other way?

I have the percentage, 50%, what calculation do I do to tell me that 50% of 90 is 45?

Thanks

It's OK, got it now.

Remember School House Rock? - conjunction junction what's you're function and all that. Maybe I'm just old.

What Percent * What Amount = How Much

So if you have the percent (.5) times the amount (90) = 45

If you need What Amount and have How Much and What Percent, you would need to divide both sides of the equal sign by What Percent, it then becomes

What Amount = How Much / What Percent or

What Amount = 45 / .5 = 90

etcetera...
