Explicație pas cu pas:

a) (2+10)/2=12/2=6

b) (3+5+16)/3=24/3=8

c) (12+30+41+13)/4=96/4=24

d) (2+0,5)/2=25/10 ÷2= 5/2•1/2=5/4

e) (0,4+2+7+0,5)3=99/10÷3=99/10•1/3=3,3

f) (0,25+0,7+0,21+0,3)/4=146/100•1/4=146/400=73/200

g)(5+0,3+0,5)3=58/10•1/3=58/30=29/15

h) (0,5+0.125+0,8)3=1425/1000•1/3=375/1000=0,375

i) (1+5+2+3+3+75+5+2)/8= 96/8=48/4=12

Daca am gresit undeva scuze, doar ca nu se intelege unde este virgula si unde este virgula pentru zecimale
