Answer 1

Răspuns:

$2. \: a)2 \frac{1}{3} \times \frac{4}{7} + \frac{9}{5} \div 3 - \frac{1}{12} =$

$2 \times 3 + 1 = 6 + 1 = 7$

$\frac{7}{3} \times \frac{4}{7} + \frac{9}{5} \div \frac{3}{1} - \frac{1}{12}$

$\frac{7}{3} \times \frac{4}{7} = \frac{4}{3}$

$\frac{9}{5} \div \frac{3}{1} = \frac{9}{5} \times \frac{1}{3} = \frac{3}{5}$

$\frac{4}{3} + \frac{3}{5} - \frac{1}{2} = \frac{20}{15} + \frac{9}{15} = \frac{29}{15} - \frac{1}{12} = \frac{348}{180} - \frac{15}{180} = \frac{348 - 15}{180} = \frac{333}{180}$
