Question

va rog mult am nevoie de ajutor...la cel mai bun raspuns dau coronita

Answer 1

(7+2.5)/2=9.5/2=4.75
(8+3.8+9.2)/3=21/3=7
aduni cate numere sunt si suma o imparti la numarul lor
(4.75+6.25+7+5.2)/4=23.2/4=5.8
s.a.m.d.

ex. 2
(a+b)/2=5.14
(a+b)=5.14*2=10.28

(a+b+c)3=7.56
(a+b+c)=7.56*3=22.68

(a+b)/2=7/2
(a+b)=7/2*2=7

(a+b+c+d+e)/5=12.32
(a+b+c+d+e)=12.32*5=61.6

(a+b+c+d)/4=9.15
(a+b+c+d)=9.15*4=36.6

(a+b+c+d+e+f+g+h+i+j+k)/10=39.85
(a+b+c+d+e+f+g+h+i+j+k)=39.85*10=398.5
