A ballet troupe has 28 dancers, including 4 new members. Express the ratio of new members to the total number of dancers in the simplest fraction for.

112

Step-by-step explanation:

so what you do is that you do 28*4 and then will get you your answer

28:4

Step-by-step explanation:

Why because 28 is how much dancer are and 4 is how many new dancers are

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: -1
