22. Adding fractions is easy!
3/8 + 1/16
Denominators must match, so 8 x what = 16?
Okay, multiply the denominator by 2
8 X 2 = 16
Whatever you do to the bottom…
You have to do to the top. So…
now multiply the numerator by 2
3 X 2 = So, 3/8 is the same as 6/16
Now add 6/16 and 1/16

23. Well?
6/16 + 1/16 =
7/16!
I told you it was easy!

24. Try it yourself!
3/4 + 3/16 =
4 x what = 16?
4 x 4 = 16
3 x 4 = 12
12/16 + 3/16 = 15/16

25. One more! 1/2 + 5/16 = How will you change 1/2 to ?/16
What times 2 = 16?
8 x 2 = 16 and 8 x 1 = 8 so 8/16 = 1/2
8/16 + 5/16 = ?
13/16 right?

26. Remember!
Think three times
Measure twice
Cut once
