13. Persentase robotik = 100 - (30+20+13+10+12)
= 100 - 85
= 15%
Robotik = 15% × 200
= 15/100 × 200 (coret 100 dengan 200)
= 30 anak (a)

14. Persentase drama = 360 - (90+100+80+60)
= 360 - 330
= 30°
Drama = 30/80 × 48
= 1440/80
= 18 anak (d)

15. persentase IPA = 360 - (45+90+81)
= 360 - 216
= 144
B.indo = 81/144 × 32
= 2592/144
= 18 orang (c)
