Answer 1

a )

13 dam + 170 dm = ? m

13 dam = 130 m

170 dm = 17 m

130 m + 17 m = 147 m

-------------------------------------

9 km + 15 m = ? dm

9 km = 90000 dm

15 m = 150 dm

90000 dm + 150 dm = 90150 dm

-------------------------------------------------

63 hm - 1300 cm = ? m

63 hm = 6300 m

1300 cm = 1,3 m

6300 m - 1,3 m = 6298,7 m

-------------------------------------------------

18 dm - 5 cm = ? mm

18 dm = 1800 mm

5 cm = 50 mm

1800 mm - 50 mm = 1750 mm

------------------------------------------------

b )

13 km + 400 dm = ? dam

13 km = 1300 dam

400 dm = 4 dam

1300 dam + 4 dam = 1304 dam

-----------------------------------------------

23 hm - 4000 dm = ? dam

23 hm = 230 dam

4000 dm = 40 dam

230 dam - 40 dam = 190 dam

-------------------------------------------------

63 hm - 1300 cm = ? m

63 hm = 6300 m

1300 cm = 13 m

6300 m - 13 m = 6287 m

-------------------------------------------------

18 dm - 5 cm = ? dm

18 dm = 18 dm

5 cm = 0,5 dm

18 dm - 0,5 dm = 17,5 dm
