20kg 5g =......kg

4 tấn 2 yến =........kg

230 kg = ........... tấn=.......... tấn

260m=..................km=....................km

430m=..............hm=..................m

4km 8m=...........km=..............km

20km 500m=....................km=.............km

3dam 7dm=...................dam

3 tấn 25kg=..................tấn=..............tấn

2kg 35 g= ...................kg=..........kg

Answer 1

\(20kg5g=20\dfrac{5}{1000}kg\)

\(4\) tấn \(2\) yến=\(4020kg\)

\(230kg=\dfrac{230}{1000}\) tấn \(=\dfrac{23}{100}\) tấn

\(260m=\dfrac{260}{1000}km=\dfrac{26}{100}km\)

\(430m=4hm30m\)

\(4km8m=4\dfrac{8}{1000}km=4\dfrac{1}{125}km\)

\(20km500m=20\dfrac{500}{1000}km=20\dfrac{5}{10}km\)

\(3dam7dm=3\dfrac{7}{100}dam\)

\(3\) tấn \(25kg=3\dfrac{25}{1000}\) tấn \(=3\dfrac{5}{200}\) tấn

\(2kg35g=2\dfrac{35}{1000}kg=2\dfrac{7}{200}kg\)
