You can put this solution on YOUR website! There is a way that "non-math" types prefer, but I can't remember it. Maybe someone else will contribute that method. I prefer to just set up an equation, where x is the unknown number, and solve for x.
First, "50%" means .50, "what #" means x, and "is" means equals.
The equation reads:
To solve for x, just divide both sides by .50
Use a calculator, or multiply numerator and denominator by 10 to get 300/5.
You can put this solution on YOUR website! read my percentage lessons that i have written on this site. However, apart from that, just from a common sense approach, don't you know the answer?
