Question

find A:B:C when a:b =3:4 and b:c 6:11
who will give me write answers I will follow them ​

Answer 1

So firstly we can see that —————→ a/b=3/4

Thus b=4a/3

Now notice that b/c=6/11 , then ———-> b=6c/11

Now substitute to get 4a/3=6c/11

Thus c=44a/18

So we want ————-> a:b:c

express b and c in terms of a

thus a:4a/3:44a/18

Multiply all sides by 18 to get

18:24:44
