Answer:

1.   228 parents

Step-by-step explanation:

I will do number 1 for you.  I'll let you or someone else do the others.

Let 10x = no. of girls

      5x = no. of boys

      4x = no. of parents

Now, 10x + 5x + 4x = 1083

                        19x = 1083

                            x = 57

(10)(57) = 570 girls

(5)(57) = 285 boys

(4)(57) = <u>228 parents</u>

             1083  total
