Question

Se da sirul de rap egale x/7=y/5=40/z.Determinatix,y si z stiind ca x×y=12

Answer 1

[tex] \frac{x}{7 } [/tex]=$\frac{y}{5}$=$\frac{40}{z}$
daca x×y=12 ⇒ $\frac{x}{7}= \frac{y}{5}$⇒$\frac{x ori y}{5x7}$=[tex] \frac{12}{35 } [/tex]=$\frac{4}{7}$
$\frac{4}{7}= \frac{40}{z}$⇒z=70
$\frac{4}{7} = \frac{y}{5}$⇒y=$\frac{20}{7}$
$\frac{4}{7} = \frac{x}{7}$⇒x=4
