Please solve it

D e a r s t u d e n t, Q . 1 \div \frac{4}{7} - \frac{1}{3} o f 3 \frac{3}{4} + \frac{1}{2} \div 3 \Rightarrow 1 \div \frac{4}{7} - \frac{1}{3} \times 3 \frac{3}{4} + \frac{1}{2} \div 3 \Rightarrow 1 \times \frac{7}{4} - (\frac{1}{3} \times \frac{15}{4}) + (\frac{1}{2} \times \frac{1}{3}) \Rightarrow \frac{7}{4} - \frac{5}{4} + \frac{1}{6} \Rightarrow \frac{21 - 15 + 2}{12} \Rightarrow \frac{6 + 2}{12} \Rightarrow \frac{8}{12} = \frac{2 \times 4}{3 \times 4} = \frac{2}{3} R e g a r d s
