Answer 2

`45m=4500cm`

`98mm=9,8cm`

`=>45m98mm=4500+9,8=4509,8 m`

`-----------------`

`770cm=7,7m`

`89mm=0,089m`

`=>770cm89mm=7,7 + 0,089=7,789m`

`--------------`

`23dam=2,3hm`

`12dm=0,012hm`

`=> 23dam12dm=2,3 + 0,012= 2,312hm`

`--------------`

`38m=3,8dam`

`92dm=0,92dam`

`=>38m92dm=3,8 + 0,92=4,72dam`

`----------------`

`31km=31000m`

`45hm=4500m`

`=> 31km45hm= 31000+4500=35500m`
