2. Logan has enough material to make 6 shirts!

Logan is making t-shirts for his buddies and has 4 yards of material. If each shirt needs 2/3 of a yard, how many shirts can he make?
Logan has enough material to make 6 shirts!

3. 4 1 3 2 2 3 12 2 x ÷ 6 = = Now here is the math…
Set your problem up like normal. 4 1 3 2 2 3 12 2 x ÷ 6 = =
Same Change Change
Now here is the trick…we NEVER divide fractions! We just FLIP the second fraction over and multiply! It’s called the RECIPROCAL!!!

4. Raven has a 12ft. Board and needs to pieces that are 5/8 ft
Raven has a 12ft. Board and needs to pieces that are 5/8 ft. How many pieces will he have? 8 5 12 1 5 8 96 5 x ÷ =
Same Change Change 1 9 1 5 19
5 √ 96 -5 4 6
- 45 1

5. REMEMBER…you only flip the SECOND fraction!!!2 4 5 10 1 1 10 8 1 x ÷ = 8 1
Same Change Change
Pretty easy stuff…eh??!! Just remember that Mr. P is the BESTEST teacher in the WORLD!!!

6. OK, lets review the different ways to divide fractions

We just FLIP over the 2nd fraction and multiply instead.
This is called the reciprocal 2 3 3 2 1 7 7 1
