Question

A+b+c=232 a÷b=14,5 b÷c=7,1 afla nr va rog

Answer 1

$a+b+c=232$
$\frac{a}{b} =14,5$⇒[tex]a=14,5*b [/tex]
$\frac{b}{c} =7,1$⇒$c= \frac{b}{7,1}$
$a+b+c=232$⇒$14,5b+b+ \frac{b}{7,1} =232$⇒$14,5*7,1b+7,1b+b=232*7,1$⇒$102,95b+7,1b+b=1647,2$⇒$111,05b=1647,20$⇒$b= \frac{1647,2}{111,05} = \frac{16472}{10} * \frac{100}{11105} = \frac{164720}{11105} =14,833$
$a=14,5*14,833=215,079$
$c= \frac{14,833}{7,1} =2.089$
Verificare:
$a+b+c=14,833+215,079+2,089=232$
