La prima il poti afla pe "a" astfel:
[tex]a = \frac{2 \times 6}{3} = \frac{12}{3} = 4[/tex]
La a doua:
[tex]b = \frac{5 \times 28}{10} = \frac{140}{10} = 14[/tex]
La a treia:
[tex]c = \frac{4 \times 9}{2} = \frac{36}{2} = 18[/tex]
La a patra:
[tex]d = \frac{5 \times 24}{12} = \frac{120}{12} = 10[/tex]
