a) 0,0253hm +5dam+340cm+890mm=
0,0253hm= 2,53m
5dam=50m
340cm=3,4m
890mm=0,89m
2,53+50+3,4+0,89=56,82m
b) 560cm²+0,025m²+47.690mm²=
560cm²=0,056m²
47.690mm²=0,04769m²
0,056+0,025+0,04769= 0,12869m²
c) 2L+12dm³+0,01m³=
2L=2dm³=0,002m³
12dm³=0,012m²
0,002+0,012+0,01= 0,024m³
d) 450dL+78.034mL=
450dL= 45L
78.034mL= 78,034L
45+78,034= 123,034L
e) 2h 30min 45s -1h 45min 55s=
1h 89min 105s- 1h 45min 55s= 44min 50s
! DEOARECE :
1min=60s
1h=60min
