If A:B=6:7andB:C=8:9, then find A:B:C.?

Question

If A:B=6:7andB:C=8:9, then find A:B:C.?

Answer 1

A:B:C = 1 :  (6/7)  :  (21/16)

THATS IT!

Answer 2

A/B= 6/7,  B=7A/6.

B/C= 8/9, B= 8C/9.= 7A/6

   C/A= 63/48, A= 48C/63.= (48into8B/9)/63.

  A=  (384 B)/ 567.

Answer 3

a/b = 6/7  @ b/c = 8/9 then a/c = 16/21 then A:B:C = 7:8:12

Answer 4

A:B = 6:7   &   B:C=8:9

As B is the common term in both a ratios

Multiply ratio 1 by 8 and ratio 2 by 7 so that Ratios of B can be equated.

48:56  & 56:63

then it becomes  A:B:C = 48:56:63

Answer 5

A/B = 6/7

B/C = 8/9

Multiplying both the equations,

A/C = 16/21

Putting A = 6, we get

C = 63/8

So, ratio is 6:7:63/8

Multiplying by 8, we get

A:B:C = 48:56:63

Answer 7

A:B=6:7 ==> 7A = 6B => A = (6/7)B

B:C=8:9 ==> 8c = 9B => C =(9/8)B

Hence A:B:C = (6/7) : 1: (9/8) = 48 : 56 : 63

Answer 8

A = 48

B = 56

C = 63

Answer 9

Answer 11

If A : B =6:7

  B:C=8 : 9 , WE SEE IN THESE RATIO B IS COMMON SO YOU WILL EQUAL THE VALUE OF "B"

       A : B =6:7 (MUNTIPLIED BY 8)

       B : C=8 : 9  (MUNTIPLIED BY 7)

SO, WE GET

     A : B : C =48 : 56 :63

Answer 12

A:B=6/7=48/56

B:C=8/9=56/63

A:B:C==48:56:63
