Tolong bantuin donk dari no 2-10 pliss

no 2=13×4=limapuluhdua

2. 13/25 x 4/4 = 22/100 = 0.22
3. 5/10 x 5/4 = 25/40
25/40 : 25/100 = 25/40 x 100/25 = 2500/1000 = 2,5
4. diskon = 120.000 x 15/100 = 18.000
harga membayar = 120.000 - 18.000 = 102.000
9. tertinggi = 9 terendah = 6. selisih = 9-6 = 3
10. rata rata = (6.3)+(7.3)+(5.2)+(4.1)+(8.2)+(9.1)/12 = 18+21+10+4+16+9/12 = 78/12 = 6,5
bnyak dibawah rata2 = 4 = 1 Orang
5 = 2 Orang. jadi banyak yang mendapt di bawah rata rata = 3 orng.

semoga membantu..
