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.
