ex 8 va rog frumos.. ​

Answer 1

Răspuns:

a) 2/7; b) 2/5; c) 5/16; d) 11/2; e) 2/5; f) 3

Explicație pas cu pas:

$\frac{ \frac{3}{5} }{2 \frac{1}{10} } = \frac{ \frac{3}{5} }{ \frac{21}{10} } = \frac{3}{5} \div \frac{21}{10} = \frac{3}{5} \times \frac{10}{21} = \frac{3}{5} \times \frac{2 \times 5}{3 \times 7} = \frac{2}{7}$

$\frac{ \frac{8}{13} }{ \frac{40}{26} } = \frac{8}{13} \div \frac{40}{26} = \frac{8}{13} \times \frac{26}{40} = \frac{2}{5}$

$\frac{1}{ \frac{16}{5} } = 1 \div \frac{16}{5} = \frac{5}{16}$

$\frac{3}{ \frac{6}{11} } = 3 \div \frac{6}{11} = 3 \times \frac{11}{6} = \frac{11}{2} = 5 \frac{1}{2}$

$\frac{ \frac{1}{7} }{ \frac{5}{14} } = \frac{1}{7} \div \frac{5}{14} = \frac{1}{7} \times \frac{14}{5} = \frac{2}{5}$

$\frac{3 \frac{1}{7} }{ \frac{22}{21} } = \frac{22}{7} \div \frac{22}{21} = \frac{22}{7} \times \frac{21}{22} = \frac{21}{7} = 3$
