Answer 2

Answer:

Hola..

Step-by-step explanation:

a:b = 7:5

b:c = 9:11

Now, we have to make the value of b Same in both the ratio's, So we will multiply by 9 to make the value same.

a:b= 7x9:9x5 = 63:45

b:c = 9x5:11x5 = 45:55

Hence, now we can see the value of b is same in the Ratio's.

So,

a:b:c = 63:45:55
