Well first do 20 children minus 8 girls to find how many boys there are: 20-8=16 So there are 16 boys. Therefore we can write the ratio of girls to boys as: 8/16 Then we can simplify this ratio by dividing it by 8 to get: 1/2 So the answer is the ratio of girls to boys in the group in simplest form is 1/2.
Y=-1/2x+5 slope=-1/2 because it goes down one unit and to the right 2 units, and the y intercept is 5 because that's where the line intercepts the y-axis!
If you take 3/4 and add it to 1/4 you get 1 then you at 1+1+2=4 then you add the lemon ie which is 2/4, therefore, the answer is 4 2/4 or 4 1/2(simplified).
Parallel lines are lines which have the exact same slope but different y-intercepts. This means any line which is parallel and does not cross will have the exact same slope of -1/6.
