Skills assignment #2; Subtracting Fractions

Friday, April 17, 2009
A few weeks ago now, we were given yet another skills assignment (skills post), still having to do with fractions. But instead we have to be able to make a post about subtracting fractions that should borrow, and fractions that should be improper fractions.
The proper time to borrow is when... one of the mixed numbers is too big. We can subtract fractions to make them improper or if the mixed numbers in the mixed fractions are too big we can just borrow.

100 2/4 - 6 3/4

The proper time to use the improper way is when... the numbers are small and when you can't take something larger from something smaller.
