Question

a:b+c=5:9
then a:b:c=?​

Answer 1

Answer:

10:18 may be................

Answer 2

Answer:

the answer is 6:5:3

Step-by-step explanation:

Now b:a+c=3:4

let,b=3k......eq1

a+c=4k

again,

a:b+c=5:9

let a=5q.......eq2

b+c=9q

or3k+c=9q from eq1...........eq3

and 5q+c=4k from eq2

or 4k-c=5q..........eq4

adding eq3 and 4

we get

7k= 14q

or k=2q

therefore

b=6q

a= 5q

and from eq4

4k-c=5q

8q-c=5q

c= 3q

and therefore

a:b:c=6:5:3
