a: \(\dfrac{P}{Q}=\dfrac{R}{S}\)
nên \(\dfrac{P}{Q}+1=\dfrac{R}{S}+1\)
hay \(\dfrac{P+Q}{Q}=\dfrac{R+S}{S}\)
b: P/Q=R/S=k
=>P=Qk; R=Sk
\(\dfrac{P}{Q-P}=\dfrac{Qk}{Q-Q\cdot k}=\dfrac{k}{1-k}\)
\(\dfrac{R}{S-R}=\dfrac{S\cdot k}{S-S\cdot k}=\dfrac{k}{1-k}\)
Do đó: \(\dfrac{P}{Q-P}=\dfrac{R}{S-R}\)

a)
\(\dfrac{P}{Q}=\dfrac{R}{S}\Rightarrow PS=QR\)
\(\Leftrightarrow PS+QS=QR+QS\)
\(\Leftrightarrow S\left(P+Q\right)=Q\left(R+S\right)\)
điều kiện Q,s khác 0 => chia hau vế cho QS
\(\Leftrightarrow\dfrac{S\left(P+Q\right)}{QS}=\dfrac{Q\left(R+S\right)}{QS}\Leftrightarrow\dfrac{\left(P+Q\right)}{Q}=\dfrac{\left(R+S\right)}{S}\) đpcm
