Not totally sure about this, but.....

 

If a : b  is  5 : 6  there are 11 equal parts

If b : c  is 8 : 9  there are 17 equal parts

 

And the common denominator is  11 * 17  = 187

 

So  a possible value for  b  = (6/11) * 187  =  102

 

But c  =  (9/8)b  =  102 * 9/8  =  114.75

But c needs to be an integer

So...mutiplying this by 4 will give us the integer 459

 

So....multiplying b by 4   we get 102 * 4 =  408

 

And  a  is  (5/6)b  =  (5/6)(408)  =  340

 

So

 

a , b , c  =    340, 408, 459

 

And   a: b   =  340: 408   =  5/6     And  b : c  =  408: 459

 

So....a + b + c  =     340 + 408 + 459   =   1207

 

 

cool cool cool
