1/2 + 2/3 + 3/4 = 23/12 we are doing this because they gave a + b + c = 789.
So, we have to calculate a ,b , c values individually and at last we want a value so (a/total * given) == 1/2 (because we want 1st part value) ÷ 23/12 after solving this we get 6/23 now 6/23 * 789(given).

Hi, friends see here, please.
12 is common in all the denominator's table.
So multiply by 12 to all denominator.
i.e. (1/2)*12 = 6.
i.e. (2/3)*12 = 8.
i.e. (3/4)*12 = 9.
That's it.

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.

According to me, the solution is;
First, calculate the ratio= 1/2+2/3+3/4 = 23/12.
Now, we know the total is 782 Rs.
So the 1st part will be 783*1/2*12/23 = 204 Rs.

6 : 8 : 9 ?
6/8 = 9/x.
6x = 9×8.
x = 9×8/6.
x = 12.
6/8 = 9/x.
6x = 9×8.
x = 9×8/6.
x = 12.

1/2x + 2/3x + 3/4x = 782.
LCM of denominators i.e 2,3,4 is 12.
(6+8+9)x / 12 = 782.
23x/12 = 782.
x=(782 * 12)/23.
Therefore x=408.
First part= (1/2)x = 408/2 = 204.
