Aw, come on, Matthew!

Today we took more notes and had more in-depth conversations about adding/subtracting mixed numbers/fractions.  We got up right to the last example (Ex 4 below) and ran into a road block!  What to do when you can't take away? How do you borrow from the whole number?

And, we ran out of time before I could share the secret!!  So, if you know the answer, please keep the secret with me... at least until Monday! :)
