Answer 1

$(( \frac{4}{5} + \frac{5}{6} \times \frac{3}{25} ) \div \frac{9}{2} - \frac{1}{15}) \times 3 \frac{3}{4} + \frac{1}{2}$

$(( \frac{4}{5} + \frac{1}{2} \times \frac{1}{5}) \times \frac{9}{2} - \frac{1}{15}) \times 3 \times \frac{3}{4} + \frac{1}{2}$

$(( \frac{4}{5} + \frac{1}{10}) \div \frac{9}{2} - \frac{1}{15} ) \times 3 \times \frac{3}{4} + \frac{1}{2}$

$( \frac{9}{10} \times \frac{9}{2} - \frac{1}{15}) \times 3 \times \frac{3}{4} + \frac{1}{2}$

$( \frac{81}{20} - \frac{1}{15}) \times 3 \times \frac{3}{4} + \frac{1}{2}$

$\frac{239}{60} \times 3 \times \frac{3}{4} + \frac{1}{2}$

$\frac{239}{20} \times \frac{3}{4} + \frac{1}{2}$

$\frac{717}{80} + \frac{1}{2}$

$\frac{757}{80}$
