Change fraction into units.
Make the numerators the same.
LCM of 8, 2 and 4 = 8
8 x 19 x 1 of the men =
2 x 43 x 4 of the women =
4 x 29 x 2 of the children
89 of the men =
812 of the women =
818 of the children
Men : Women : Children
9 : 12 : 18

(c)
Number of children = 18 u
(d)
Difference between the number of women and men
= 12 u - 9 u
= 3 u
