Answer 1

$a) \frac{25}{12} \times \frac{4}{5} = \frac{5}{ 3}$

$b) \frac{16}{9} \times \frac{3}{8} = \frac{2}{3}$

$c) \frac{18}{35} \times \frac{7}{36} = \frac{1}{10}$

$d)( - \frac{28}{15} ) \times \frac{5}{21} = - \frac{4}{9}$

$e) \frac{25}{18} \times ( - \frac{9}{10} ) = - \frac{5}{4}$

$f)( - \frac{ 15}{14} ) \times \frac{7}{25} = - \frac{3}{10}$

Answer 2

Explicație pas cu pas:

a)

$\frac{25}{12} \div \frac{5}{4 } = \frac{25}{12} \times \frac{4}{5} = \frac{5}{3 }$

b)

$\frac{16}{9} \div \frac{8}{3} = \frac{16}{9} \times \frac{3}{8} = \frac{2}{3}$

c)

$\frac{18}{35} \div \frac{36}{7 } = \frac{18}{35} \times \frac{7}{36} = \frac{1}{10}$

d)

$( - \frac{28}{15} ) \div \frac{21}{5} = ( - \frac{28}{15}) \times \frac{5}{21} = - \frac{4}{9}$

e)

$\frac{25}{18} \div ( - \frac{9}{10} ) = - \frac{5}{4}$

f)

$( - \frac{15}{14} ) \div \frac{7}{25} = - \frac{3}{10}$

baftă!
