Question

3.238\(m^2\)=.........\(dm^2\)      4789cm=.....dm              1997mm=............m

0.21\(m^2\)=...........\(dm^2\)      1m6dm=.....m                 1001mm=............m

 

Answer 1

\(3,238m^2=323,8dm^2\\ 0,21m^2=21dm^2\\ 4789cm=478,9dm\\ 1m6dm=1,6m\\ 1997mm=1,997m\\ 1001mm=1,001m\)

Answer 2

\(3,238m^2=323,8dm^2\)
\(0,21m^2=21dm^2\)
\(4789cm=478,9dm\)
\(1m6dm=1,6m\)
\(1997mm=1,997m\)
\(1001mm=1,001m\)

Answer 3

`3,238m^2=3,238xx100=323,8dm^2`

`0,21m^2=0,21xx100=21dm^2`

`4789cm=4789:10=478,9dm`

`1m6dm=1+6:10=1,6m`

`1997mm=1997:1000=1,997m`

`1001mm=1001:1000=1,0001m`

Answer 4

\(3,238m^2=323,8dm^2\)

\(0,21m^2=21dm^2\)

`4789cm = 478,9dm`

`1m6dm = 1,6m`

`1997mm = 1,997m`

`1001mm = 1,001m`

Answer 5

3.238m²=323.8     4789cm=478.9dm              1997mm=1.997m

0.21=21      1m6dm=1,6m                 1001mm=1.001m
