Question

porfa es urgente!! a cuánto equivalen las letras a/3 = b/15 = c/21 sabiendo que a+b+c= 24

Answer 1

$\frac{a}{3}=\frac{b}{15}=\frac{c}{21} = \frac{a+b+c}{3+15+21}$

$DATO : a +b +c = 24\ ; entonces$

$\frac{a}{3}= \frac{b}{15}= \frac{c}{21} = \frac{24}{39}$

-----------------------------------------------------------------------

$\frac{a}{3} = \frac{24}{39} --> a = \frac{24}{13}$

$\frac{b}{15} = \frac{24}{39} --> b = \frac{120}{13}$

$\frac{c}{21} = \frac{24}{39} --> c =\frac{168}{13}$

----------------------------------------------------------------------------

y eso es todo , espero se entienda xD

SALUDOS!!
