Answer:

n = 3

Step-by-step explanation:

there are 80 people in choir

half are women , that is 40

quarter of number of women are men , that is 10

number of children = 80 - 40 - 10 = 80 - 50 = 30

number of children : number of men = 30 : 10 ( divide both parts by 10 )

children : men = 30 : 10 = 3 : 1 ← in simplest form

with n = 3

Answer:

30

Step-by-step explanation:

=> number of people in the choir = 80

=> number of women in the choir =  half the total people = 80/2 = 40

=> number of men in the choir = one quarter of the number of women =

   (1/4)*40 = 40/4 = 10

=> for the number of children,

    we subtract the sum of number of men and women from the total            

    people  = 80 - (40+10)      =        80 - 50 = 30

           number of children = 30

hope this helps :)
