Please help with this math question!

7/8 divided by 2 1/4=?

Sorry I am mobile and don't have the division sign. I worked it out and got what I think it the right answer but the key said it isn't. Please help! Thanks!

7/8    /   9/4 = 7/8    /  18/8 =7/18 (8th)  = .038/8  or is this when you reverse them?  like 7/8 * 8/18.  Heck, I have forgotten after all these years.  Guess I am too old for these problems.  So good luck if you are working with your kids.  I used to know this.  Guess I need to talk to my daughter about this as she is starting to work with her daughter and she was a statistic s/computer major in college.  Good luck.  This grandmother  used to know this but I haven't used this for a long time.

7/8 /  2 1/4 = 7/8 / 9/4

7/8 x 4/9 = 28/72 = 7/18 or 0.3889

What answer did you get?

You are right. The answer key is wrong!

I got 7/18 too. Maybe it's a misprint in the book?
