    Mad, I am 64 and have hated maths all my life (mildly terrified of it) but these lessons are so good , its actually fun , how come no teacher I encountered ever made it so easy and so interesting, thankyou very much these 'basics' are really helpful, thank you !!

      Yes , I've learnt more since leaving school than I did in school, when I was around 10 , my maths teacher would cane us when we didn't get enough correct answers, sometimes I was afraid to go to school , because my teacher was a bully , luckily my family moved to Australia from the uk when I was twelve, my teach there, recognized my learning difficulties, and spent extra time with me, no caning , always thankful to Mr keim for saving me , I became a builder running my own business, I taught myself about cos and tan , it helped a lot with setting out roof angles, when you have a practical application in maths , it makes it more interesting. I'm 70 now and still learning.

    There is a better shortcut trick for converting mixed recurring decimals to fractions. Take for example the last number shown : 0.91666....
    Step 1: Subtract the number 916 by the number formed by non repeating digits i.e 91
    => 916-91 = 825
    Step 2: Divide the number above by a number formed by taking as many 9's as the number of repeating digits and add as many trailing zeroes as there are digits after the decimal which are not repeating
    => 825/900 = 11/12

    With regard to the problem 0.9166666...., there is the following option so that you have easier calculations.
    0.9 = 9/10 and .0166666....=1/6 but our problem was slightly different. So if we divide 0.16666.... by 10, it becomes 0.016666.... = 1/60.
    So merely add 9/10 and 1/60, which equals 55/60 that reduces to 11/12.

    Hi Josh thank you so much for this video very useful? I have a question for you, I came a cross with decimal 0.3846153846 How do you get to its fraction 5/13? I found this one difficult.

    • @tecmath
      @tecmath  2 หลายเดือนก่อน

      Thanks for the question...
      For 0.3846153846 the repeat is 384615.
      As a fraction this is therefore 384615/999999, which after a bunch of simplification becomes 5/13.

    I love when I hear people say they hate math or are terrified by it. To me that just means your teachers are bad at explaining or don’t know how to teach it. Math comprehension is completely related to the teacher. I had a teacher go through the proof of an equation and it completely confused the whole class. During break I went up to the board and erased the whole thing but the actual equation and in 2 mins said this part means this and this part means this. The whole class was sitting there dumbfounded realizing that the teacher wasted an hour on something that needed maybe 3 sentences to convey.

      Multiply 25 by 4 to get 100.
      1800 consists of 18 hundreds
      18 × 4
      to mentally calculate this, double it twice. 18 -> 36 -> 72
      there is still 75 left (1800 vs 1875). Add 3 that you get from 75/25

    A similar method is to do this:
    0.732424242424
    Take the total decimal pattern right up until you start repeating (including the repeated part), i.e. 7324
    Then subtract the part that isn't repeated, i.e. 7324 - 73 = 7251
    This is the numerator.
    The denominator will be a number that has the same number of 9s as the repeated pattern's digits, followed by the same number of 0s as the non-repeated pattern's digits
    The repeated pattern is 24 (two digits), and the non-repeated pattern is 73 (two digits), therefore, the denominator is 9900.
    So, 0.73242424.... = 7251 / 9900, which can be "simplified" to 2417 / 3300 - of course I use the term "simplified" loosely.
    And just to prove this wasn't a fluke, here's another example:
    0.8472195195195195195195....
    Take the decimal part up to, and including the repeated part, i.e. 8472195
    Then subtract the non-repeated part, i.e. 8472195 - 8472 = 8463723 (this will be the numerator)
    Now, we take the repeated part, which is 195, and put the same number of 9s as the number of digits in the repeated part, i.e. 999
    Then we take the non-repeated part, which is 8472, and put the same number of 0s as there are digits in the non-repeated part, after the 999, to get 9990000.
    Therefore, 0.8472195195195195... = 8463723 / 9990000, which, like the last one, can also be "simplified" to 2821241 / 3330000.... again, "simplified" is used very loosely.
