# Thread: Mixed numbers word problem

1. ## Mixed numbers word problem

If you lose $\displaystyle 3\frac{1}{2}$pounds the first week of your diet and $\displaystyle 2\frac{2}{3}$pounds the second week, how many
pounds do you still need to lose to reach your goal of losing 10 pounds?

Answer(provided): $\displaystyle 9\frac{1}{10}$

To my belief pounds to reach goals = 10 - total lost
which in this case would be 10 - ($\displaystyle 2\frac{2}{3} + 3\frac{1}{2}$)
Which is 10 - ($\displaystyle \frac{7}{2}+\frac{8}{3}$)
Which is 10 - $\displaystyle \frac{37}{6}$
Which is $\displaystyle \frac{23}{6} = 3\frac{5}{6}$

Why am I wrong, what might I be thinking opposite to what is actually right?

Thanks

What you have written is correct, provided that you have copied the question down correctly.

Yup. That's what I got too.

Then why is the correct answer, according to the test answers, $\displaystyle 9\frac{1}{10}$?

I kept thinking that this was some kind of trick question or something.

Either the answers are wrong, or you have read the answer to a different question, or you have copied the question wrong.

Mr. Prove it, you indeed proved it. I was going back and forth between the pages and I was reading three answers ahead.
So I was right, so I'm really not low on my pre-algebra skills. I don't even know why am I reviewing this unit.
