a) ce ptocent reprezinta 4y-3x din 5y-4x
b) ce procent reprezinta 5y-4x din 4y-3x

Answer 1

[tex]daca\;\;\frac{x}{y}=\frac{6^{(2}}{10}=\frac{3}{5}\rightarrow\;\frac{x}{3}=\frac{y}{5}=k\Rightarrow\;x=3k\;\;si\;\;y=5k;\\ a)\;...\Rightarrow\;\;\frac{4*5k-3*3k}{5*5k-4*3k}=\frac{11k}{13k} \approx85/100\;;\\ b)\;...\Rightarrow\;\;\frac{5*5k-4*3k}{4*5k-3*3k}=\frac{13k}{11k}\approx118/100 ;[/tex]
