Adding and subtracting Fractions

Storyboard Text

  • Psst! what is 2/6 plus 7/12
  • Figure it out yourself!You can use the 4 square method.
  • In the first square you write the question down. So in your case you'd write 2/6 plus 7/12 
  • Then with what ever you got you find out the denominator times what equals their LCD
  • Then in the second square you find the LCD. Lowest common denominator. You find the denominators' multiples and stop until you find the lowest multiple that they have in common.
  • So now you should have two fractions with the same denominator. So the problem should be easier!
  • And whatever you multiply the denominator by, you also multiply the numerator. You do this on both fractions
  • What are you doing!?!?
  • Nothing!!!!!!!!
  • Just be calm.
