urgent multumesc

Answer 1

a) 2,5m²+1,2dam²=.0,025dam²+1,2dam²=1,225dam²
b)1,5km²+17200ari=15000arii+17200arii=322ha
c) 6000cm²+...m²=60dm²+?=12dm²   ceva e gresit
d)5ha+0,3km²-....hm²=50000m²+300000m²-345.700m²=4300m²
e)0,0002hm-...m²+48dam²=20000dm²-    +480000dm²=2300dm² ceva e gresit
f)583dm²+.....m²+1300cm²=5,83m²+ 1,04m²+0,13m²=7m²
