Calculați media aritmetică a numerelor :
a) 12; 18; 24; b) 1/2; 3/4; 2/5; 1/6;
c) 0,30; 1,20; 4,5;
d) 24; 5/2; 3,5; 1,(3);

Răspuns :

Gly
a) [tex]\dfrac{12+18+24}{3}[/tex]=[tex]\dfrac{54}{3}[/tex]=simplifici cu 3=18

b) [tex]\dfrac{[tex]\dfrac{1}{2}+{3}{4}+{2}{5}+{1}{6}}{4}[/tex]=[tex]\dfrac{109}{240}[/tex]

c) [tex]\dfrac{0,30+1,20+4,5}{3}[/tex]=[tex]\dfrac{6}{3}[/tex]=2

d) [tex]\dfrac{24+[tex]\dfrac{5}{2}+3,5+1,(3)}{4}[/tex]=[tex]\dfrac{188}{32}[/tex]=simplifici cu 4=[tex]\dfrac{47}{6}[/tex]
