Regrouping to Subtract Mixed Numbers
This is the 3rd vid on Subtracting Mixed Numbers. When the fractions part of a mixed number subtraction doesn't work out the way you want, mostly it's quickest to make improper fractions. But in THIS video, the problem posed has BIG whole number parts. I mean this thing would be a BEAST if you made these into improper fractions!!
So we make use of regrouping instead and have a nice easy time, thanks very much.
This is presented in a way that I think ALL students will get.
