      Yes. This is a necessary skill, but I almost always dislike equations that don't actually have an answer. Although, memorizing equations you just need to insert the actual values in are very handy.
      He's a good teacher for those who are just learning. I haven't had a mathematics class in decade and do these in my head.

      @@rampakeshbharat1938 He could be a lot better, but I once had a math teacher in public school that made him look like a genius. Luckily I managed to get transferred to another class were they actually taught the subject and made it fun to boot.

    [a/5] : [7/c] = a · c / 5 · 7 = ac/35
    -----------------------------------------------------
    [5a/3b] : [30b/9a] = [5a · 9a] / [3b · 30b]
    [5a · 9a] / [3b · 30b] = 45a²/90b² = a²/2b²✅

    =(45a^2)/(90b^2)=
    =a^2/(2b^2)=1/2(a^2/b^2)

    If we're dividing by 30b / 9a then that means multiplying by 9a / 30b.
    So the numerator is 5a × 9a = 45a²
    Denominator is 3b × 30b = 90b²
    We can cancel a factor of 45 from numerator and denominator, leaving a² / 2b².
    But that's simplifying, not solving.

    When I see
    "÷ X"
    I replace it with
    "× (1/X)"
    so
    (5a/3b) ÷ (30b/9a)
    becomes
    (5a/3b) × (9a/30b)
    = (5/30)(9/3)(a^2/b^2)
    = (1/6)(3)(a^2/b^2)
    = (1/2)(a^2/b^2)

    The answer is NO.
    I cannot solve it until I get more information.
    But I can simplify it.

    Alright, let’s do this.
    (5a / 3b) / (30b / 9a)
    Before anything else, division by a fraction? How about multiplication by the reciprocal, much better!
    (5a / 3b) * (9a / 30b)
    Now, welcome to the cancel party. 5 and 30 reduce to 1 and 6, while 3 and 9 reduce to 1 and 3:
    (1a / 1b) * (3a / 6b)
    (a / b) * (3a / 6b)
    The party ain’t over till I say it’s over! The remaining 3 and 6 reduce to 1 and 2:
    (a/b)*(1a/2b)
    (a/b) * (a/2b)
    Now the cancel party is over. All that is left is to multiply:
    (a * a) / (b * 2b)
    a^2 / (2b^2)
    And that’s it. Simple, yes?
