20 dm + 32 cm = ? mm​

Answer 1

Explicație pas cu pas:

6 dam + 23 m

= 60 m + 23 m

= 83 m

12 km + 15 dam

= 12000 m + 150 m

= 12150 m

12 hm + 63 dam

= 1200 m + 630 m

= 1830 m

19 hm + 55 dam

= 1900 m + 550 m

= 2450 m

192 m + 208 m

= 19,2 dam + 20,8 dam

= 40 dam

20 dm + 32 cm

= 2000 mm + 320 mm

= 2320 mm
