Answer 1

a) 273 cm/3+17000 mm/3=... dm3
transformam
0,273 dm/3+0,017 dm/3=....dm3
=0,290 dm3

b)83· 1000 dm3 +143.000.000 mm3=....m3
83.000m3+0,143m3=.....m3
83 m3+ 0,143 m3=.....m3
83,143 m3


c)0,7105 hm3+ 3·121 m3+ 4 dam3=....dam 3
710,5 dam 3+ 363 m3+4 dam3=.....dam3
710,5 dam3+ 0,363 dam3+4 dam3=....dam3
714,863 dam3


d)71·10/4m3+ 1,31 hm3-785dam3=....hm3
710.000 m3+ 1,31 hm3-0,785 hm 3=....hm3
0,71 hm3+ 1,31 hm3-0,785 hm3=....hm 3
2,02 hm3-0,785 hm3=......hm3
1,235 hm3


e) 3,970 cm3 - 0,00097 m3 +15 · 10/5 mm3=..dm3
3,97dm3-0,97 dm3+15·100.000 mm3=....dm3
3+1.500.000 mm3=....dm3
3+ 1,5=....dm3
4,5 dm3


f)4,2 hm3 -0,0002 km3+ 6000m3=...dam3
4200dam3-200dam3+6 dam3=....dam3
4000dam3+6dam3=....dam 3
4006 dam 3
