  • Forget finding common denominators when subtracting dissimilar fractions - this way is much faster and easier. This video also looks at how to deal with mixed numbers and simplification. Oh yeah..and at the end can you beat me? Not a chance!

Thought I had saved your videos, but didn’t, and all I could remember was it was the “Australian guy” who taught me- can’t believe I found you again! Thank you so much for making math easy for me!

      @@patriotjon8535 Well, for one thing just knowing you understand and can solve the fractions is a great feeling and, second, maybe you can help someone else who is struggling with fractions. For myself, I will be confident doing fractions and I will be able to help my grandson if he needs it. I've always been afraid of math because I didn't understand it and I've always thought I was inept at math, but now I know I just never had anyone who knew how to teach it so I could understand it. Have a GREAT day! :)

    • @chocolateangel8743
      @chocolateangel8743 3 года назад +1

      That's not surprising. I've seen videos in which high school math teachers (have to take calculus and higher-level math to teach) have admitted that they didn't really understand fractions until they had taught for a while. These days, the standards for math educators have been raised. They actually have to understand concepts, math logic, and be able to see problems from multiple perspectives.
      Simply memorizing the standard algorithm isn't good enough, anymore. I've even seen some math teachers with shirts that say, "Math is a language," which is how I personally view it. If you want to have an even better understanding of fractions, I recommend you check out Dr. James Tanton here on RUclips. He is quite creative and visual and does things outside-of-the-box.

  • @bambamnj
    @bambamnj 2 года назад +3

    for mixed numbers I've always resolved the whole numbers first and this way I only have to convert one side of the problem to an improper fraction. so based on your first example:
    2 1/4 - 1 1/3 - First I would just subtract out the whole numbers so 2 - 1 = 1
    my equation now becomes 1 1/4 - 1/3 - now I convert the 1 1/4 to an improper fraction which gives me 5/4
    my equation is now 5/4 - 1/3 now make them have the common denominator, so 5/4 becomes 15/12 and 1/3 becomes 4/12
    my final equation becomes 15/12 - 4/12 which equals 11/12
