    One of the best explanations. Can't understand why professors have such hard time explaining this, looks so simple here! Thanks a lot.

    It would be nice if one day we get to the place where we can celebrate a job well done by one educator, without turning around and shitting on others.

    @@roobiki4494 It's a valid criticism of other educators. Especially considering that the most arrogant and self-righteous ones are always the worst at teaching.

    In the last example he wanted 1180/482. Using a ;pocket calculator this reduces to 241/590. Write out the continued fraction representation = [2, 2, 4, 3, 8] and underneath write the convergents, = [1/2, 2/5, 9/22, 29/ 71, 241/590] For an odd number of convergents (we have 5), the rule is to extract the denominatlor to the left of the rightmost denominator, that is, 71. That's the answer as stated in the lesson.
