  2. Let’s Review Regrouping • What does it mean when we regroup to subtract two numbers? • Basic Subtraction Regrouping

  3. Fraction Regrouping If we can borrow one ten to make ten ones, then we can also borrow one whole to make fractions. = =

  4. Subtracting with Regrouping 4 5 5 5 4 5 1 5 3 2 = 2 = One of these wholes must be broken up into fifths so that we subtract. 4 5

  5. Subtracting with Regrouping 4 5 5 5 4 5 1 5 3 2 = 2 = How you break up the whole depends on the denominator.

  6. 1 2 2 4 3 4 3 4 5 5 = 2 2 2 4 One of the wholes must be broken up into fourths. 3 4 You can’t take away from . Now, we can subtract. Answer: 3 4 2
