if a: b c=3 4:7 then the ratio (a+b+c) then the c ?is equal to

if a: b c=3 4:7 then the ratio (a+b+c) then the c ?is equal to

Explanation

 if a : b : c : = 3 : 4 : 7

the ratio of ( a + b+ c) : c

 (a + b+ c) 

= 3 + 4 + 7

= 14

(a + b+ c) : c

= 14: 7

= 2: 1

The ratio (a + b + c) ∶ c is equal to 2: 1
