2. 224 is 25% of what number?
We're looking for a much larger number. Think: one dollar is 25% of 4 dollars
0.25w = 224
w = 224/0.25
w = 896

224 is 25% of what number
you are told that 224 is 1/4 of a number. The number must be 4 times as big as 224.
56 is 1/4 of 224
224 is 1/4 of 896
algebraically,
224 = .25 x
224/.25 = x
x = 896
it always helps to write down each step, then check your answer.
you answered the question
"25% of 224 is what?"
not "225 is 25% of what?"

Jman -- you first need to show us that you've gone back and really studied your math text. Try these problems again, and explain why you did what you did.
