Question

Va rog ajutati-ma trebuie sa o predau azi cu tot cu rezolvare dau coroana

Answer 1

2 intregi si 1/3= (2×3+1)/3=(6+1)/3=7/3;
3 intregi si 1/2=(3×2+1)/2=(6+1)/2=7/2;

2 intregi si 1/3 + 3 intregi si 1/2=
7/3 +7/2=
{amplificam fractia 7/3 cu 2 si fractia 7/2 cu 3}
=14/6 +21/6=(14+21)/6=35/6= 5 intregi si 5/6

Answer 2

$2\dfrac{1}{3} +3\dfrac{1}{2} = 2+\dfrac{1}{3}+3+\dfrac{1}{2} = 5+^{\big{2)}}\dfrac{1}{3}+^{\big{3)}}\dfrac{1}{2} = 5+\dfrac{2+3}{6} = 5+\dfrac{5}{6} = \\ \\ = 5\dfrac{5}{6} = \dfrac{5\times 6+5}{6} = \dfrac{35}{6}$
