Given :1/2:2/3:3/4=782
Let x b a part of 782 whn divided into 3 parts
(1/2)x:(2/3)x:(3/4)x=782
Take lcm we get
(6x+8x+9x)/12=782
23x=782*12
x=9384/23=408
Now we need 1 part so (1/2)*408 = 204.
Let x b a part of 782 whn divided into 3 parts
(1/2)x:(2/3)x:(3/4)x=782
Take lcm we get
(6x+8x+9x)/12=782
23x=782*12
x=9384/23=408
Now we need 1 part so (1/2)*408 = 204.

1:2 is multiplyed by 6/6 then it will be 6/12,in second case 2:3 is multiplyed by 4/4 then 8/12, and 3:4 multyplyed by 3/3 then 9/12; it is done because of doing denominators equal,new ratio becomes 6:8:9.

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

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

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.

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 ?
