Question

Comparati numerele $\frac{3}{17} si \frac{4}{19}$ aducand fractiile la acelasi numitor.

Answer 1

I.    aducem fractiile la numitor comun  , adica: [17;19]=323 ;
II.   amplificam fractiile ...
                  $\frac{^{19)}3}{17}=\frac{57}{323} \;\;si\;\;\frac{^{17)}4}{19}=\frac{68}{323}\\ \\ 57\,\ \textless \ \,68\;\;\rightarrow\;\;\frac{57}{323}\ \textless \ \frac{68}{323}\\ deci\;\;\;\frac{3}{17}\ \textless \ \frac{4}{19}$
