1. 11hm3 - 110.000m3 = ... dam3 2. 15dm3 + 8000 cm3 = ... dl 3. 21l - 180cl = ... ml 4. 46.000ml + 2800dl = ... L 5. 9L - 7000cm2 = ... dm3

1) (11 × 1000) - (110000 ÷ 1000) = 11000 - 110 = 10890 dam^3

2) (15 × 10) + (8000 ÷ 100) = 150 + 80 = 230 dl

3) (21 × 1000) - (180 × 10) = 21000 - 1800 = 19200 ml

4) (46000 ÷ 1000) + (2800 ÷ 10) = 46 + 280 = 326 l

5) (9 × 1) - (7000 ÷ 1000) = 9 - 7 = 2 dm^3

semoga membantu

1. 11 hm3 = 11.000 dam3
110.000 m3 = 110 dam3

11.000 dam3 - 110 dam3 = 10.890 dam3

2. 15 dm3 = 150 dl
8000 cm = 80 dl

150 dl + 80 dl = 230 dl

3. 21 l = 21000 ml
180 cl = 1800 ml

21000 ml - 1800 ml = 19.200 ml

4. 46000 ml = 46 l
2800 dl = 280 l

46 l + 280 l = 326 l

5. 9 l = 9 dm3
7000 cm = 700 dm3

9 dm - 700 dm = 691 dm
