Số học sinh trung học cơ sở là:
480 x 2/3 = 320 (em)
Số học sinh trung học phổ thông là:
1000 - 480 - 320 = 200 (em)
a, Số học sinh tiểu học chiếm:
480 : 1000 = 0,48 = 48% (số học sinh toàn trường)
b, Số học sinh trung học cơ sở chiếm:
320 : 1000 = 0,32 = 32% (số học sinh toàn trường)
c, Số học sinh trung học phổ thông chiếm:
200 : 1000 = 0,2 = 20% (số học sinh toàn trường)
