Question

Номер:6 Сократите дроби. -35/49 2)-91/-39 3) 77/-42 4) -125/175

Answer 1

$\frac{ - 35}{ - 49} = \frac{7 \times 5}{7 \times 7} = \frac{5}{7}$

$\frac{ - 91}{ - 39} = \frac{13 \times 7}{13 \times 3} = \frac{7}{3} = 2 \frac{1}{3}$

$\frac{77}{ - 42} = - \frac{11 \times 7}{6 \times 7} = - \frac{11}{6} = - 1 \frac{5}{6}$

$\frac{ - 125}{175} = - \frac{25 \times 5}{25 \times 7} = - \frac{5}{7}$
