Answer:
5:3
Step-by-step explanation:
So, ratio of girls to boys is 20:12 . You can reduce this ratio, the same way you reduce a fraction. Both numbers have a common fact of 4 , so divide both by 4 . In simplest form, this ratio is 5:3 .

Step-by-step explanation:
-1., 1, 2, 2
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14
Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98
Therefore:
1/7 divided by 1/98 will give us 14
Average rate=(change in y)/(change in x)
if f(x)=-x/3
r=( f(2)-f(-2) )/(2--2)
r=(-2/3-2/3)/(2+2)
r=(-4/3)/4
r=-4/12
r=-1/3
For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
