Bună,
[tex]a)3 \times \frac{7}{2} = \frac{21}{2} \\ b)5 \div \frac{1}{3} = 5 \times 3 = 15 \\ c)4 \times \frac{2}{7} = \frac{8}{7} \\ d)6 \div \frac{3}{7} = 6 \times \frac{7}{3} = 2 \times 7 = 14 \\ [/tex]
[tex]e) \frac{7}{9} \times 2 = \frac{14}{9} \\ f) \frac{11}{3 } \div 5 = \frac{11}{3} \times \frac{1}{5} = \frac{11}{15} \\ g) \frac{14}{5} \times 5 = 14 \\ h) \frac{ 21}{3} \div 2 = 7 \times \frac{1}{2} = \frac{7}{2} \\ [/tex]
[tex]i) \frac{27}{13} \times 3 = \frac{81}{13} [/tex]
Sper că te-am ajutat
