Answer 1

Answer: 6:10:13

Step-by-step explanation:

A : B = 3:5

B : C = 10:13

A:B = 3:5 ---- (1)

B:C = 10:13.------(2)

Find LCM of values of B  

i.e. 5 and 10

5  |  5 ,10

2  |  1 ,2

   |  1 , 1

LCM= 5*2 = 10

So multiply (1) by 2

So A:B:C  = 6:10:13

Hence A:B:C = 6:10:13

OR

A:B = 3:5 (1)

B:C = 10:13. (2)

So LCM of both values of B = 5 and 10 = 10

So multiply (1) by 2

So A:B:C

= 6:10:13 , which is in the simplest ratio

Hence A:B:C = 6:10:13

OR

B:C = 10:13. (2)
