First I want to say that I must apologize if this problem is in the incorrect part of the board. I honestly could not figure out what area this problem would fall under.
If anyone read my intro a good while back, I'm in college and have to take basic college mathematics before I can get to core classes because I chose to pay literally no attention to class when I was in high school. Anyways this was the one problem I got incorrect on my Math midterm. I realized that the way to solve this was SO easy, but I decided to post this so I can get some feedback on whether I did it correctly (I'm positive this time that I did) and also to give my first attempt at the Latex thing.
Anyways the word problem goes as such.
"A frame that is 18 inches by 24 inches has a mat in it that is 2 1/4 inches all around. What are the dimensions of the picture within the mat?"
I took a photo of the picture, I hope the quality is decent enough.
thus the answer is 13.5 by 19.5
2 1/4 + 2 1/4 = 4.5
18 - 4.5 = 13.5
24 - 4.5 = 19.5
What say you?
