Question

Daca 2a supra 3b=3 supra 10, atunci b supra a =

Answer 1

$\frac{2a}{3b} = \frac{3}{10} \Longrightarrow 2a \times 10 = 3b \times 3 \Longrightarrow \\ \\ \Longrightarrow 20a=9b \Longrightarrow \boxed{\frac{b}{a} = \frac{20}{9} }$

Answer 2

$\frac{2a}{3b}= \frac{3}{10}=\ \textgreater \ 20a=9b=\ \textgreater \ \frac{b}{a} = \frac{20}{9}$
