Answer 2

Salut!:)

Efectuați:

a)4/7+2/7=6/7

b)3/8+2/8=5/8

c)7/11+3/11=10/11

d)19/100+37/100=56/100

e)11/25+2/25+9/25=22/25

f)32/75+29/75+14/75=75/75(întreg)

g)4/22+5/22+6/22+7/22=22/22(întreg)

h)4/22+5/22+6/22+7/2=22/22(întreg)

i)1/55+2/55+3/55+...+10/55=?

Aplic metoda lui Gauss:n×(n+1):2⇒n=10

10×(10+1):2=10×11:2=110:2=55⇒55/55(întreg)
