Va roggg !! Am nevoie pana maine dimineata

Answer 1

a) 2500cm= 25m
   0.0075 km=7,5m
  2500cm+0.0075km= 25m+ 7.5m=32.5m 
b)3800mm=3,8m
   2150mm=2,15m
  3800mm+2150mm=3,8m + 2.15m = 5.95m
c)420dam=4200m
  18000dm=1800m
   420dam + 18000dm= 6000m
d)1500cm=15m
   0.05hm=5m
  1500cm+ 0.05hm=20 m
e)480mm=0.48m
   20cm=0,2 m
  480mm+20cm+0.68
f)0.05mm=0.00005m
  100hm=10000
 0.05mm +100hm=10000.00005m
