Question

Aflati numarul rational x, stiind ca x:$\frac{3}{4} = \frac{16}{27}$

Answer 1

 $x\,:\,\frac{3}{4}=\frac{16}{27}\;\;\Rightarrow\;\;x=\underbrace{\frac{16}{27}\cdot\frac{3}{4}}_{am\,simplificat\\cu 3\,si\,4}}=\frac{4}{9}$

Answer 2

cand imparti doua fractii prima se pastreaza dar a doua se inverseaza si impartirea devine inmultire
Tu o sa ai 
x * 4/3=16/27
4x/3=16/27
4x*27=16*3
108x=48
x=48/108  simplificam prin 2
x=24/54  simplificam prin 6
x=4/9
