Question

Si: a/2 = b/3= c/5 y a + b + c= 100; Halla "a"

Answer 1

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

a=2k
b=3k
c=5k

a+b+c =100
2k+3k+5k =100
10k = 100
k=10

a = 2k = 2(10)  = 20

a = 20 

Answer 2

Respuesta:

20

Explicación paso a paso:

a=2k

b=3k

c=5k

a+b+c =100

2k+3k+5k =100

10k = 100

k=10

a = 2k = 2(10)  = 20

a = 20
