Question

If A:B=1/2:1/3,B:C=1/5:1/3, then(A+B):(B+C)is equal to

Answer 1

it should be your answer.

Answer 2

Answer: Our required ratio would be 15: 16.

Step-by-step explanation:

Since we have given that

a:b = $\dfrac{1}{2}:\dfrac{1}{3}=3:2$

b:c = $\dfrac{1}{5}:\dfrac{1}{3}=3:5$

So, we can write it as

a : b  : c

3 : 2

    3  : 5

-------------------------------

9 : 6 : 10

So, (a+b) : (b+c)

= (9+6) : ( 6+ 10)

= 15 : 16

Hence, our required ratio would be 15: 16.
