Question

Meeeeeee aaaajjjuuuuuudeeeemm !!!!!!!!
Resolver a proporção a\3=b\5=c/2, sabendo que a+b+c=200 por favor me ajudem preciso para hoje!!!

Answer 1

$\dfrac{a}{3}=\dfrac{b}{5}=\dfrac{c}{2}$

$b=\dfrac{5a}{3}$ e $c=\dfrac{2a}{3}$

$a+b+c=200$

$a+\dfrac{5a}{3}+\dfrac{2a}{3}=200$

$3a+5a+2a=600$

$10a=600$

$a=60$

$b=\dfrac{5\cdot60}{3}=100$

$c=\dfrac{2\cdot60}{3}=40$

$\dfrac{60}{3}=\dfrac{100}{5}=\dfrac{40}{2}=20$
