• Is not this the same as common denominators? good luck and good learning
• These are not same denominators, but In this video you try to get the same denominators in order to add or subtract. Good luck to you too!
• At couldn't you carry over like normal?
• You are correct you could. however, this lesson is called "Adding mixed numbers with regrouping", so the point is to learn this specific strategy
• I found a glitch where you will get double points if you restart it. you could have infinite energy points.
• Really?
• Converting mixed numbers to fractions
• To convert a mixed number to an improper fraction, you have to multiply the whole number by the denominator (number on the bottom) then add the numerator (number on the top).
• thanks =)
• thanks for the video! =)
