no. 16 sampai 27 dan caranya Terima kasih

16. 1,8 km - 1600 m + 400 dm =
= 1,8 × 100 = 180
=1600 : 10 = 160
=180 - 160 = 20
400 : 100 = 4 + 20 = 24 a

17. 1,6 ton+15 kuintal+2,1 ton - 35 kuintal
1,6 ton × 1000 = 1600
15 × 100 = 1599
2,1 × 1000 =2100
= 5200
35 × 100 = 3599 - 5200 = 1700 b
19. 12 kodi + 12 lembar + 2 1/4
12 × 20 = 240
12 = 12 + 240 = 252
2×20 = 40
1/4 × 20 = 5 + 40 = 45
253 + 45 = 297 d
udah y smp sini aja
