2ha 4m2=.......ha                           49,83dm=........m

8ha 7dm2=.......m2                         249,7cm2=........ha

16m2 213cm2=......m2                    8417cm2=.......m2

9,587=..........m2                              75dm2=.........ha

Answer 1

`2ha 4m^2 = 2 + 4 : 10000 = 2,0004ha`

`8ha 7dm^2 = 8 +7 : 1 000 000=8,000007ha`

`16m^2 213cm^2 = 16 + 213 : 10000 = 16,0213m^2`

`9,587` đơn vị j ?

`49,83dm = 49,83 : 10 = 4,983m`

`249,7cm^2 = 249,7 : 100000000=0,000002497ha`

`8417cm^2 = 8417 : 10000 = 0,8417 m^2`

`75dm^2 = 75 : 1 000 000 = 0,000075ha`

Answer 2

`2ha 4m^2 = 2 + 4 : 10000 = 2,0004ha`

`8ha 7dm^2 = 8 xx 10000 + 7 : 100=80000,07m^2 `

`16m^2 213cm^2 = 16 + 213 : 10000 = 16,0213m^2`

`9,587` đơn vị j ?

`49,83dm = 49,83 : 10 = 4,983m`

`249,7cm^2 = 249,7 : 100000000=0,000002497ha`

`8417cm^2 = 8417 : 10000 = 0,8417 m^2`

`75dm^2 = 75 : 1 000 000 = 0,000075ha`

Answer 3

2ha 4m² = 2,0004 ha

8ha 7dm² = 8,000007 ha

16m² 213 cm² = 16,0213 m²

9,587? = ....?.... m²

49,83 dm = 4,983 m

249,7 cm² = 0,000002497 ha

8417 cm² = 0,8417 m²

75 dm² = 0,000075 ha
