Answer 1

a)

305 m - 17 000 mm + 430 dm = ? m

= 305 m - 17 m + 43 m =

= 288 m + 43 m =

= 331 m

b)

600 mm +25 cm+ 3 m=? cm

= 60 cm + 25 cm + 300 cm =

= 85 cm + 300 cm =

= 385 cm

c)

960 cm - 6 m + 58 dm - 1 200 mm = ?dm

= 96 dm - 60 dm + 58 dm - 12 dm =

= 36 dm + 58 dm - 12 dm =

= 94 dm - 12 dm =

= 82 dm

d)

800 m - 2 700 cm -3 500 dm +7 000 mm =?m

= 800 m - 27 m - 350 m + 7 m =

= 773 m - 350 m + 7 m =

= 423 m + 7 m =

= 430 m
