Explicație pas cu pas:
2 - 1/2 = 4/2 - 1/2 = 3/2
3/2 : 1/2 = 3/2 x 2/1 = 6/2 = 3
Salut!
Rezolvare:
[tex](2 - \frac{1}{2} ) \div \frac{1}{2} = 3[/tex]
[tex]2 - \frac{1}{2} = \frac{4}{2} - \frac{1}{2} = \frac{3}{2} [/tex]
[tex] \frac{3}{2} \div \frac{1}{2} = \frac{3}{2} \times \frac{2}{1} = \frac{6}{2} = 3[/tex]
