See their value is 1/2:2/3:3/4
Then take LCM 2,3,4 it's come 12
Then, (1/2:2/3:3/4)/12
Then 12/2=6 then 6*1=6
12/3=4 then 4*2=8
12/4=3 then 3*3=9
This way we find the 6:8:9.

The given ratios are=1/2:2/3:3/4
Then take the LCM Of the denominator of ratios(2,3,4=12)
Then divide each ratio with 12. for eg:- 1/2*12=6.

Hello @Varsha.
Take LCM of 3 we get 12 that's it.

First We have to calculate LCM of 2,3,4. We get as 12.
Multiply each ratio i.e. numerator and denominator by 12 then we get ratio as 6:8:9.
Then calculate first part as {(782*6)/23} = 204 as answer.

1/2 = 50%.
2/3 = 66.67%.
3/4 = 75%.
____________
191.
982 x 50/191 = 204.
2/3 = 66.67%.
3/4 = 75%.
____________
191.
982 x 50/191 = 204.
