Question

determinati numerele naturale x,y,z stiind ca fractiile x supra 36,12 supra y,9 supra 6, 30 supra z sunt reprezebtanti ai aceluiasi numar rational

Answer 1

        
$\frac{x}{36}= \frac{12}{y}= \frac{9}{6}=\frac{30}{z} \\ \\ \frac{x}{36}= \frac{9}{6} \;\;\;\;\; =>x= \frac{36*9}{6}=6*9=\boxed{54} \\ \\ \frac{12}{y}= \frac{9}{6};\;\;\;\; =>y= \frac{12*6}{9}=4*2=\boxed{8} \\ \\ \frac{30}{z}= \frac{9}{6};\;\;\;\; =>z= \frac{30*6}{9}=10*2=\boxed{20}$
