tolong jawab ya kalau nggak bisa jawab nggak usah jawab +poin

6. kpk 36/42/48
36 = 2pangkat2 × 3pangkat2
42 = 2 × 3 × 7
48 = 2pangkat4× 3
kpk = 2pangkat4 × 3pangkat2 × 7
= 16×9×7 = 1008

10.fpb 40/60/100
40 = 2pangkat3 × 5
60 = 2pangkat2 × 3 × 5
100 = 2pangkat2 × 5pangkat2
fpb = 2pangkat2 × 5 = 20

12. 60km/45mnt
1 menit = ? km
w : 3 jam 15 menit
: 195menit
60÷45 = 1,33km/mnt

13. t =( L÷( a+b) ) × 2
= (400÷(24+16)) × 2
= (400÷40)×2
= 10 × 2 = 20

14. 25 - (-35) = n
n = 60
