Answer:

48 students

Step-by-step explanation:

Girls who sing : girls who don't sing = 1 : 2

Let total number of girl be x

Part of girls who sing = (1/3)x

Part of girls who sing = 8

                              [tex]\frac{1}{3}x=8\\\\x =8*\frac{3}{1}\\[/tex]

                             x = 24

Number of girls = 24

Girls : boys = 1 : 1

Number of boys = number of girls

Total students in the show = 24 + 24 = 48
