If `(a)/(3)=(b)/(4)=(c)/(7)` find `(a+b+c)/(c)`

If (a)/(3)=(b)/(4)=(c)/(7), then (a+b+c)/(c) is

If (a)/(3)=(b)/(4)=(c)/(7), the value of (a+b+c)-:c is (a) (1)/(7)(b)(1)/(2)(c)2(d)7

a//3=b//4=c//7 then find (a+b+c)//c .

If a/3 = b/4 = c/7 then (a+b+c)/(c) is equal to

If a :b::3:4 & b:c:: 4:7. then (a +b + c)/( c ) = ?

If (7a + 8b)/( 7c + 8d) = (7a - 8b)/(7c - 8d), prove that : (i) a:b=c:d (ii) (4a - 5b)/(4c - 5d)= (3a + 4b)/(3c + 4d)
