F.) 20 m = 20×10 = 200 dm

270 cm = 270:10 = 27 dm

= 200 dm + 120 dm – 27 dm

= 293 dm ✔

g.) 25 m = 25×1.000 = 25.000 mm

= 1.500+25.000

= 26.500 mm ✔

h.) 5 km = 5×100 = 500 dam

12 hm = 12×10 = 120 dam

= 500-120-6

= 374 dam ✔

i.) 75 km = 75×100 = 7.500 dam

12 hm = 12×10 = 120 dam

150 m = 150:10 = 15 dam

= 7.500-120+15

= 7.395 dam ✔

j.) 6,2 km = 6,2×1.000 = 6.200 m

22 hm = 22×100 = 2.200

= 6.200-2.200-3.750

= 250 m ✔
