Question

cum determinam daca fractia este mai mare, egala sau mai mica?

Answer 1

$\dfrac{a}{b} = k \Longrightarrow a=bk$

$\dfrac{a}{b} = 1 \ \Longrightarrow a = b$

$\dfrac{a}{b}\ \textgreater \ k \ \Longrightarrow a\ \textgreater \ bk$

$\dfrac{a}{b} \ \textgreater \ 1 \ \Longrightarrow a\ \textgreater \ b$

Answer 2

aduci la numitor comun si compari numaratorii
