Question

calculati 1pe 3:2la2+1pe6

Answer 1

1\3:2²+1\6=
1\3:4+1\6=
1\3x1\4+1\6=
1\12+1\6=1+2\12=3\12=1\4
succes

Answer 2

(1/3):2²+1/6=(1/3):4+1/6=(1/3):(4/1)+1/6=(1/3)*(1/4)+1/6=(1*1)/(3*4) +1/6=
1/12+1/6=1/12+2/12=(1+2)/12=3/12=1/4


la efectuiarea calculului, am aplicat succesiv si dupa caz, ordinea operatiilor, impartirea fractiilor ordinare,inmultirea fractiilor ordinare,  aducerea fractiilor  la acelasi numitor(amplificarea ), adunarea fractiilor cu acelasi numitor, simplificarea
