Question

va rog frumos din suflet urgent​

Answer 1

Explicație pas cu pas:

$\frac{1}{3} - \frac{3}{1}$

$\frac{3}{4} - \frac{4}{3}$

$\frac{5}{6} - \frac{6}{5}$

$\frac{2}{9} - \frac{9}{2}$

$\frac{8}{7} - \frac{7}{8}$

$1 \frac{4}{5} = \frac{1 \times 5 + 4}{5} = \frac{9}{5} \\ \frac{9}{5} - \frac{5}{9}$

$3 \frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{13}{4} \\ \frac{13}{4} - \frac{4}{13}$

$5 \frac{2}{7} = \frac{5 \times 7 + 2}{7} = \frac{37}{7} \\ \frac{37}{7} - \frac{7}{37}$

$2 \frac{3}{10} = \frac{2 \times 10 + 3}{10} = \frac{23}{10} \\ \frac{23}{10} - \frac{10}{23}$

$10 \frac{5}{11} = \frac{10 \times 11 + 5}{11} = \frac{115}{11} \\ \frac{115}{11} - \frac{11}{115}$

$7 \frac{2}{3} = \frac{7 \times 3 + 2}{3} = \frac{23}{3} \\ \frac{23}{3} - \frac{3}{23}$
