a)
[tex]1.5 \times 3 = \frac{15}{10} \times 3 = \frac{15 \times 3}{10} = { \frac{45}{10} }^{(5} = \frac{9}{2} = 4.5[/tex]
b)
[tex] \frac{12}{15} \div ( - \frac{5}{3} ) = \frac{12}{15} \times ( - \frac{3}{5} ) = - { \frac{36}{75} }^{(3} = - \frac{12}{25} = 0.48[/tex]
c)
[tex]2 \frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3} = 2.(3)[/tex]
Sper ca te-am ajutat :))))))
