Question

. Find a:b:c if a:b=5:4 and b:c=8:5 


​

Answer 1

Answer:

Step-by-step explanation:

  a/b = 5/4

  4a = 5b ......equation(1)

  now b/c = 8/5

  5b = 8c  ....... equation(2)

  we know that 5b = 4a from equation(1)

  so 4a = 8c

   thus a = 2c

   b = 8c/5

now a:b:c = (2c) : (8c/5) : c

       a:b:c = 2:8/5:1

       a:b:c = 10 : 8 : 5

         Hope it helps you.......
