Answer 1

Răspuns:

$a ) \frac{21 \div 7}{35 \div 7} = \frac{3}{5}.... b) \frac{ \sqrt{6} \div \sqrt{3} }{2 \sqrt{3} \div \sqrt{3} } = \frac{ \sqrt{2} }{2 } \\c) \frac{4x \div 2x}{6 {x}^{2} \div 2x } = \frac{2}{3x}$

$d) \frac{ {x}^{3} \div x}{x(x + 1) \div x} = \frac{ {x}^{2} }{x + 1} \\ ...e) \frac{(x + 2) \div (x + 2)}{x(x + 2) \div (x + 2)} = \frac{1}{x}$
