Question

if a/3 =b/5 =c/7 then find the value of a+b+c/b

Answer 1

Let : a/3 = b/5 = c/7 = k

a = 3 k

b = 5 k

c = 7 k

( a + b + c ) / b

==> ( 3 k + 7 k + 5 k ) / 5 k

==> 15 k / 5 k

==> 3

The value is 3

Hope I helped

Answer 2

let
a/3 = b/5 = c/7 = K,

so when
a/3 = K,
then
a=3K,

similarly
b=5K,

c=7K,

therefore

(a+b+c)/b,

(3K+5K+7K)/5K,

15K/5K,
