1. Multiplying Mixed Numbers
Chapter 2.2D

2. ½ of 1 ½ 3 4

3. 1 Lets try multiplying like normal first… 1 2 1 2 x
NOOOOO the whole number blocked us! : (
1st multiply straight across. 1 2 1 1 2 x
We need a TOP and a BOTTOM so lets make it IMPROPER!

4. 1 3 2 1 2 + x 1st BIG times the BOTTOM Then ADD the TOP!
Here’s what we did…
1 x 2 = 2 and then = 3
Now put it BACK over 3 to make our fraction! 3 2

5. 3 4
Now we can multiply! 1 2 3 2 x
Make sure to simplify either FIRST or LAST if you can!!!

6. 3 1 2 4 3 9 4 36 12 1 3 1 4 x x = = + + x x Then ADD the TOP!
Now, do it AGAIN! 1 1 3 2 1 4 + + x x x
1st
BIG times the BOTTOM 4 3 9 4 36 12 3 x = =

7. 3 4 9 3 4 3 x = 1 Remember, you could have simplified 1st too!!!
The 4s can cancel out! 3 x = 1
The 3 and 9 can divide by 3!

8. 2 1 2 4 5 3 1 8 + x x 4 5 25 8
100 40 5 2 5 1 x = = 1 2

9. 1 3 4 2 3 2 5 8 + x x 2 3 21 8 42 24 7 4 7 1 x = = 1 4

10. 3 1 3 1 1 4 2 2 3 + + x x x 5 4 8 3 40 12 10 3 2 x = = 1

11. 11 1 3 6 4 5 1 2 3 + + x x x 34 5 5 3
170 15 34 3 x = =
