Question

5x=6y, $\frac{2x}{3y} =?$ heeeelp! dau "coroana"

Answer 1

5x=6y
⇒x=6y/5
2x/3y=2*6y:5/3y=12y:5/3y=12y/5:3y=12y/5*1/3y=12y/15y=4/5

Answer 2

5x=6y ; x= $\frac{6y}{5}$ ; $\frac{2x}{3y} = \frac{2 * \frac{6y}{5} }{3y} = \frac{ \frac{12y}{5} }{3y}= \frac{12y}{5} * \frac{1}{3y} = \frac{4}{5}$
