At first to take lcm 2:3:4 then the result is 12.
Then after multiplying 1st part 1/2 * 12 = 6.
After multiplying 2nd part is 2/3 * 12= 8.
After multiplying 3rd part is 3/4 * 12 = 9.
The result is 6 : 8 : 9 after the result add it (6 + 8 + 9) = 23.
According to question find the 1st Part.
1st part is 6 and the total number is 23.
ie, 782 * 6/23 = 204 is the correct answer.
Then after multiplying 1st part 1/2 * 12 = 6.
After multiplying 2nd part is 2/3 * 12= 8.

You can it can also be done in this way divide the fractions like 1/2 = .5, 2/3 = .66 3/4 = .75 so the ratio would be like .5 : .66 : .75 .
This can be also written as 50 : 66 : 75.
According to some rule when all ratios in the given are multiplied with same number or value, the ratio or proportion remains the same.
Now, we can find the value of the first => 50/ 191 * 782 = 204.
This can be also written as 50 : 66 : 75.

TAKE LCM(2,3,4) = 12;
THEN (6:8:9).
THEN (6:8:9).

Given data.
1/2 : 2/3 : 3/4 = 782.
=> (1/2)x:(2/3)x:(3/4)x = 782.
=> x/2 + 2x/3 + 3x/4 = 782.
L.C.M(2,3,4) = 12.
(6x+8x+9x)/12 = 782.
23x = 782 * 12.
x = 9384/23.
X = 408.
First part= (1/2) * 408 = 204.
1/2 : 2/3 : 3/4 = 782.
=> (1/2)x:(2/3)x:(3/4)x = 782.
=> x/2 + 2x/3 + 3x/4 = 782.
L.C.M(2,3,4) = 12.
(6x+8x+9x)/12 = 782.
23x = 782 * 12.
x = 9384/23.
X = 408.
First part= (1/2) * 408 = 204.

Given ratio = : : = 6 : 8 : 9.
1st part = Rs. 782 x 6 = Rs. 204.
1st part = Rs. 782 x 6 = Rs. 204.
