꧁Hello, how are you?꧂

• Respondi em cada uma delas. kk

$2.1 \times ( - \frac{1}{2} )3 + \sqrt{ \frac{225}{16} } - ( - \frac{2}{3} )2 \div ( \frac{3}{4} ) - 2 \\ \\ \frac{21}{10} \times ( - \frac{1}{2} ) \times 3 + \sqrt{ \frac{225}{16} } - ( - \frac{2}{3} ) \times 2 \div \frac{2}{4} - 2 \\ \\ \frac{21}{10} \times ( - \frac{1}{2} ) \times 3 + \frac{15}{4} - ( - \frac{2}{3} ) \times 2 \div \frac{3}{4} - 2 \\ \\ \frac{21}{10} \times ( - \frac{1}{2} ) \times 3 + \frac{15}{4} + \frac{2}{3} \times 2 \times \frac{3}{4} - 2 \\ \\ - \frac{21}{10} \times \frac{1}{2} \times 3 + \frac{15}{4} + \frac{2}{3} \times 2 \times \frac{4}{3} - 2 \\ \\ - \frac{63}{20} + \frac{15}{4} + \frac{2}{3} \times 2 \times \frac{4}{3} - 2 \\ \\ - \frac{63}{20} + \frac{15}{4} + \frac{16}{9} - 2 \\ \\ \frac{ - 567 + 675 + 320 - 360}{180} \\ \\ \frac{68}{180} \\ \\ \frac{17}{45}$
