Answer:

Step-by-step explanation:

Aviara Oaks Middle School:

Total student = 400

Boys : girls = 2:3

Boys = 2x , girls = 3x

2x + 3x = 400

       5x = 400

         x = 400/5

         x = 80

Number of boys = 2x = 2*80 = 160

Number of girls = 3x = 3 *80 = 240

VMS:

Total student = 360

Boys :  girls = 3 : 5

Number of boys = 3x

Number of girls = 5x

3x + 5x = 360

       8x = 360

        x = 360/8

       x =  45

Number of boys= 3x = 3 *45 = 135

Number of girls = 5x = 5 * 45 = 225

AOMS school has more boys attending their school.

Ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School = 240 : 225

                                    = 48 : 45
