It depends on which letter you are looking at, but in for this triangle the hypotenuse will always be AB. The adjacent side is the one “left” or “right” of the latter you’re looking at, but never the hypotenuse (stays the hypotenuse). So if you’re looking at “B”, the adjacent side is CB or 21, while AC or 20 is the opposite

The LCD = 6x^2y^3    ( because LCD of 3 and 6 = 6,  LCD of x^2 and x = x^2 and LCD of y and y^3 = y^3)
now divide 3x^2y into the LCD  then multiply this  by 5 to get the first term in the numerator  and do similar process to get second term, so we get:-
5(2y^2) - 4(x)
------------------
   6x^2y^3
=  2( 5y^2 - 2x)
   -----------------
        6x^2y^3
=    5y^2 - 2x
      -----------
      3x^2y^3
