Viết số thích hợp vào chỗ chấm:
a) \(12,44m =...m...cm\); b) \(7,4dm =...dm...cm\);
c) \(3,45km =...m\); d) \(34,3km=...m\).
a) \(12,44m =12 \frac {44}{100}m= 12m \;44cm\);
b) \(7,4dm =7 \frac {4}{10}dm= 7dm \;4cm\);
c) \(3,45km=3,450km = 3\frac {450}{1000}km\)\( = 3km\; 450m = 3450m\);
d) \(34,3km=34,300km = 34\frac {300}{1000}km\)\( = 34km\;300m = 34 300m\).
