Answer 2

Answer:

480

Step-by-step explanation:

if number of boys : number of girls = 7:8,

number of boys=7x, number of girls = 8x

total number of students = 7x+8x=15x

number of girls = 256 = 8x

                             256/8=x

                              32=x

Therefore, total number of students = 15x = 15*32 = 480
