Answer 1

Explicație pas cu pas:

a) 2,5m²+..........=1dam²=100m²

2,5m²+97,5m²=100cm²

b) 48dm²+..........=1m²=100dm²

48dm²+52dm²=100dm²

c) 27dam2+277m2+.........=1hm2

27dam²+2,77dam²+70,23dam=100dam²

d)625cm2+........=1m2

6,25dm²+75dm²=100dm²

e)318m2+277m2+.......=1hm2

3,18dam²+2,77dam²+24,05dam²=100dam²

f)21dm²+450cm²+;;=1m²

21dm²+4,5dm²+74,5dm²=100dm²
