Question

Calculati 300 mm+2dm?m 20 puncte doar sa lalculati si sa nu faceti 300+2=32 trebuie sa faceti corect mai departe e in poza

Answer 1

1) Transformam milimetrii in centimetrii
300 mm=30 cm
2 dm=20 cm
30 cm+20 cm=50 cm

2)30 dm=3 m
42 m+3 m=45 m

3)720 dam=72000 m
72000 m+5 m=72005 m

4)980 dm=98 m
98 m-8 m=90 m

5)4x32 m=128m
420 dm=42 m
128 m-42 m= 86 m

6)24 km:3=8 km
360 hm=36 km
8 km+36 km=44 km

7)68 dm:2=34 dm
570 cm =57 dm
34 dm+57 dm=91

8)72 hmx6=432 hm
300 m=3 hm
432 hm-3 hm=429 hm

9)16 dm=160 cm
160 cm+20 cm=180 cm

10)300 cm=30 dm
215 dm-30 dm=185 dm

11)800 mm:2=400 mm
400 mm=400 mm=4 dm

12)320 dmx6=1920
1920 dm= 1920 dm=192 m

Sper ca te-am ajutat!!
