Đáp án+Giải thích các bước giải:

 `7` m = `700` cm

`7` m = `70` dm `7000` mm

`1` m `7` cm = `107` cm

`----`

`2` m = `20` dm = `200` cm 

`9` m = `90` dm = `900` cm

`5` km `6` hm = `56` hm

`----`

`5` km = `500` dam `5000` m

`3` km = `30` hm `3000` m

`7` km `8` dam = `708` dam

`----`

`7` hm = `70` dam `700` m

`6` m = `6000` mm

`9` m `8` dm = `98` dm

`----`

`4` km = `40` hm `4000` m

`5000` m = `5` km

`9` m `7` cm = `907` cm

`----`

Km > hm > dam > m > dm > cm > mm
