**Ms. Sue**, Wednesday, November 14, 2012 at 2:04pm2. 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

**Steve**, Wednesday, November 14, 2012 at 2:06pm224 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?"

**Ms. Sue**, Wednesday, November 14, 2012 at 2:09pmJman -- 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.
