Answer 1

$\large\sf\underline{Answer\::}$

$\sf\:1)\:\frac{7}{5} \times \frac{5}{7}$

$\sf\to\:\frac{35}{35}$

$\sf\to\:\cancel{\frac{35}{35}}$

$\small\fbox\green{=>\:1}$

________________

$\sf\:2)\:\frac{2}{6} \times \frac{0}{1}$

$\sf\to\:\frac{0}{6}$

$\small\fbox\green{=>\:0}$

________________

$\sf\:3)\:\frac{10}{20} \times \frac{2}{1}$

$\sf\to\:\frac{20}{20}$

$\sf\to\:\cancel{\frac{20}{20}}$

$\small\fbox\green{=>\:1}$

________________

$\sf\:4)\:\frac{-2}{5} \times \frac{3}{4}$

$\sf\to\:\frac{-6}{20}$

$\sf\to\:\cancel{\frac{-6}{20}}$

$\sf\to\:\cancel{\frac{-3}{10}}$

$\small\fbox\green{=>\:-0.3}$

________________

$\sf\:5)\:\frac{6}{7} \times \frac{14}{-5}$

$\sf\to\:\frac{84}{-35}$

$\sf\to\:\cancel{\frac{84}{-35}}$

$\sf\to\:\cancel{\frac{12}{-5}}$

$\small\fbox\green{=>\:-2.4}$
