Answer 1

A) 135cm+2,55m=....m

135cm=1,35m

1,35m+2,55m= 3,90m

B) 1500cm + 270 dm - 1,4 dam = ....m

1500 cm = 15 m

270=27m

1,4dam=14m

15m + 27m + 14m = 56m

C) 185000mm - 0,025km= ....m

185000mm= 185m

0,025km=25m

185m - 25m = 160m

D) 52000mm + 140 dm - 0,13 dam = .... dm

52000mm=520dm

0,13dam=13dm

520dm + 140dm -13dm

660dm - 13dm

647dm
