@koalamon now about a hint

hint: in this equation:\[\frac{a+b}{ab}=\frac{c+d}{cd}\]divide the numerator and denominator of the lefthandside by 'b' and divide the numerator and denominator of the righthandside by 'd'.

what is componedo and dividendo???

DLS Group TitleBest ResponseYou've already chosen the best response.1
It is a theorem in which the denominator is added to the numerator & numerator is added with negative denominator e. g. if \[\frac{x}{y}=\frac{a}{b}\] then by componendo & dividendo we have \[\frac{( x + y)}{( x y ) }\]= \[\frac{( a +b )}{( a  b )}\] (Proof) \[\frac{3}{2}\] =\[\frac{ 6}{4}\] then by componendo & dividendo \[\frac{3+ 2}{32}\] = \[\frac{6 +4}{6 4}\] OR 5/ 1 = 10/ 2 that is true

@DLS do you understand asnaseer's hint???

I think the theorem is better, he just said if u do the same thing/operation with a digit on one side,u do that on other too so overall effect nullifies

you helped me greatly thanks

This is what I meant  starting with this:\[\frac{a+b}{ab}=\frac{c+d}{cd}\]lets first divide the numerator and denominator of the lefthandside by 'b' to give:\[\frac{\frac{a}{b}+1}{\frac{a}{b}1}=\frac{c+d}{cd}\]then lets divide the numerator and denominator of the righthandside by 'd' to give:\[\frac{\frac{a}{b}+1}{\frac{a}{b}1}=\frac{\frac{c}{d}+1}{\frac{c}{d}1}\]now note that you are given that:\[\frac{a}{b}=\frac{c}{d}\]so the equality of both sides follows from this relation.

I don't think you can just assume the "Componendo and dividendo" theorem directly as this question is effectively asking you to prove it.
