Multiply 1/2 with 6, 2/3 with 4 and 3/4 with 3 so that numerator is same i.e. 12, hence 6:8:9
First part is 6 upon sum of 6+8+9=23 i.e. 6/23
First part is 6 upon sum of 6+8+9=23 i.e. 6/23

How 1/2 is attained as 6 2/3 as 8 and 3/4 as 9 and how for calculating the first part the number is multiplied by 6/23 ?

The LCM of all the denominators is 12. So multiply the number and denominator with 6 to make 1/2 as 6/12, multiply 2/3 with 4. So that it becomes 8/12 and multiply 3/4 with 3 to make 9/12. Now the new ratio will be:
6/12, 8/12, 9/12.
Now cancelling 12 we will get 6, 8, 9.
6/12, 8/12, 9/12.
Now cancelling 12 we will get 6, 8, 9.

You just need to multiply every ratio by 12 because it is the lcm of denominators.

Taking lcm for 2, 3, 4 and we got 12. Then the numerators 6, 8, 9 were used.
