1-5!tulis cara nyaa! trimsss

B
1.
faktor 8 = 1,2,4,8
faktor 10 = 1,2,5,10
faktor persekutuan = 1,2
2.
faktor 12 = 1,2,3,4,6,12
faktor 20 =1,2,4,5,10,20
faktor persekutuan = 1,2,4
3
16= 1,2,4,8,16
24= 1,2,3,4,6,8,12,24
fpb= 8

kpk = 2×2×2×2×3×3
= 144
5 = 23,29

D

15 = 15,30,45,60,75,90,105
20 = 20,40,60,80,100
kelipatan persekutuan = 60
jadi jawabany adalah 60

kpk = 2 × 2 × 2 × 3 × 5(semua bilangan pembagi)
= (2×2×2) × ( 3 × 5)
= 8 × 15
= 120
fpb = 2 × 3(bilangan yang bisa membagi 24 dan 30)
= 6
4
debit = volume / waktu
= 6.000liter/ 30 menit = …m3/jam
= 6m3/30menit × 2/2
= 12m3/1jam(60menit)
= 12m3/jam
5
debit = volume / waktu
= 36 liter/ 3menit
=36liter = 36.000cm3
= 3menit = 180detik
= 36.000cm3/180detik
= 200cm3/detik
