2 How to subtract Mixed Fractions! YOU CAN DO IT!

3 5 ¼ - 1 ½ WHAT DO YOU DO? 

4 Work on the fraction side first…. 5 ¼ - 1 ½ Find the common denominator! LCD for 4 and 2 is? YES! 4!!!!!!

5 Now Remember? Whatever you do to the bottom of the fraction, you must do to the top of the fraction. You knew that already, didn’t you! 5 ¼ = 1 4 2 - 1 ½ = 4

6 Oh NO!!!!! 5 ¼ = 1 4 2 - 1 ½ = 4 The top fraction is smaller than the bottom fraction! You will need to add some of the whole number to the top fraction to make it bigger. Take a fraction that means ‘one whole’ from the whole number of 5. HOW DO YOU DO THAT? HELP !!!!!!

7 First you must take one whole group from the whole number side. Oh no! How do you do that? WATCH: 5 ¼ the fraction tells you that it takes 4 pieces to make a whole SO….If you have 5 wholes and ¼ more then you must have: 5 sets of 4 and ¼ piece more

8 Break up one of the whole pieces into ……. well…… PIECES! Add the pieces to the one piece you already had! Now your have 4 wholes and five 4 th size pieces ARE YOU CONFUSED? Hang in there …… the fun has just begun!

9 Well now you have 4 whole sets and 5 pieces it still equals 5 and ¼ it just looks different 4 5/4 NEXT STEP…. You now have enough pieces on the fraction side to subtract 2 pieces from it. 4 5 1 + 4 = 5 4 4 4 1 2 - 4 3 4

10 Now just subtract the whole numbers! 4 5 4 1 2 - 4 3 3 4 YOU DID IT!!!! I am so proud of you.
