Explicație pas cu pas:

a)

[tex] \frac{25}{12} \div \frac{5}{4 } = \frac{25}{12} \times \frac{4}{5} = \frac{5}{3 } \\ [/tex]

b)

[tex] \frac{16}{9} \div \frac{8}{3} = \frac{16}{9} \times \frac{3}{8} = \frac{2}{3} [/tex]

c)

[tex] \frac{18}{35} \div \frac{36}{7 } = \frac{18}{35} \times \frac{7}{36} = \frac{1}{10} [/tex]

d)

[tex]( - \frac{28}{15} ) \div \frac{21}{5} = ( - \frac{28}{15}) \times \frac{5}{21} = - \frac{4}{9} [/tex]

e)

[tex] \frac{25}{18} \div ( - \frac{9}{10} ) = - \frac{5}{4} [/tex]

f)

[tex]( - \frac{15}{14} ) \div \frac{7}{25} = - \frac{3}{10} [/tex]

baftă!
