28 girls
Given girls : boys ===> 7 : 12
i.e.
fraction all children who are girls = 7 / (7 + 12) = 7 / 19
fraction all children who are boys = 12 / (7 + 12) = 12 / 19
given that there are 76 children
number of girls = fraction of all children who are girls x total number of children
= 7/19 x 76
= 28 girls
y=9/6 (3/2 simplified)
2(6y-2)-3y=2
12y-4-3y=2
ad 4 both side
12y-3y=6
9y=6
9/6
40 degrees
