1. Transformaţi:
UNITĂŢI DE MĂSURĂ
a)1 dam = ? m 5 dam = ? m 24 dam = ? m
1 hm = ? m 8 hm = ? m 82 hm = ? m
1 km = ? m 6 hm = ? m 100 dam = ? m
b)1 m = ? dm 1 m = ? cm 1 m = ? mm
3 m = ? dm 4 m = ? cm 9 m = ? mm
2 m = ? dm 8 m = ? cm 7 m = ? mm
2. Calculaţi:
a) 17 m + 49 m = ? m 187 dam + 58 dam = ? dam
68 m + 32 m = ? m 386 dam + 99 dam = ? dam
98 m – 35 m = ? m 325 dam – 165 dam = ? dam
100 m – 76 m = ? m 503 dam – 168 dam = ? dam
b) 325 hm + 499 hm = ? hm 736 km + 264 km = ? km
172 hm + 428 hm = ? hm 227 km + 368 km = ? km
544 hm – 126 hm = ? hm 579 km – 259 km = ? km
900 hm – 269 hm = ? hm 841 km – 732 km = ? km
c) 922 cm + 37 cm = ? cm 648 dm – 225 dm = ? dm
108 dm + 14 dm = ? dm 250 mm – 38 mm = ? mm
128 mm + 212 mm = ? mm 92 cm – 7 cm = ? cm
363 cm + 137 cm = ? cm 591 mm – 186 mm = ? mm
d) 47 cm x 2 = ? cm 27 cm : 3 = ? cm
31 mm x 4 = ? mm 48 dm : 8 = ? dm
14 dm x 5 = ? dm 48 mm : 4 = ? mm
100 cm x 7 = ? cm 72 cm : 9 = ? cm
