1 Dividing Fractions Using Pictures!

2 First, you have to start with ½ of one whole…
½ ½ 1/2

3 How many ¼ are in ½ of our whole?
Now we divide our whole into fourths 2!!! How many ¼ are in ½ of our whole?

4 What about mixed numbers…
Let’s try Start by drawing 1 ¾ (1 whole= 4/4) (3/4)

5 Now let’s divide our picture into eighths
(1 whole= 8/8) (3/4= 6/8)

6 Now let’s see how many groups of 3/8 we can get from the shaded part (1 ¾)
So we got 4 full groups of 3 and 2 out of the 3 we needed left over…

7 But what if the first denominator is larger?
Go ahead and draw the first fraction… Let’s try

8 Since we can’t split our 9ths into 3rds, we will make our second fraction have a common denominator of 9.

9 Now let’s see how many sets of 3/9 we can get out of our shaded area (5/9)
We have one full set of 3 and 2/3 of another set…

10 Now you try! Did you start out with this? Draw

11 Did you divide into 8ths?

12 Did you find how many groups of 3 you could make?
2!

13 Let’s try another… Draw

14 Did your picture turn out like mine?
/3 Our answer=
