*** mean my answers

Please check my answers.

You have a lot of studying to do.
Your answers for 2, 4, 5, 7, 8, and 10 are wrong. 
Why is 2 wrong? i came up as a answer 56.

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 
Oh.....

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?" 
Can you or Steve help me with the others.

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.

I have an Online textbook not hardcover. It takes forever to get to the right page.

You and your parents chose this school and text; I didn't.
Now, get to work and learn what you're supposed to learn. 
I don't have parents. :(
