1. Subtracting fractions and mixed numbers with unlike denominators and with regrouping

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 Regrouping4 5 5 3 2 4 5 1 5 = 2 =
One of these wholes must be broken up into fifths so that we subtract 4 5

5. Subtracting with Regrouping4 5 5 3 2 4 5 1 5 = 2 =
How you break up the whole depends on the denominator.

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

7. 6 4 4 2 4 4 5 + 3 4 2 3 4 2
The method with picture…
