Answer 2

$\huge{\mathfrak{Answer :}}$

$\sf{15 \frac{1}{2} - [ \frac{12}{ \cancel{5}} \times \frac{ \cancel{5}}{8}+ (7 \div 1 \frac{3}{4})] \times 2 } \\ \sf{ \longrightarrow \frac{31}{2} - [ \frac{12}{8} + ( \cancel7 \div \frac{ \cancel7}{4})] \times 2 } \\ \sf{ \longrightarrow \frac{31}{2} - [ \frac{12}{8} + 4] \times 2} \\ \sf{ \longrightarrow \frac{31}{2} - [ \frac{12 + 32}{8}] \times 2} \\ \sf{ \longrightarrow \: \frac{31}{2} - \frac{ \cancel{44}}{ \cancel8} \times \cancel2} \\ \sf{ \longrightarrow \: \frac{31}{2} - 11 } \\ \sf{ \longrightarrow \: \frac{ 31 - 22}{ 2} } \\ \sf{ \boxed{ \boxed {\frac{9}{2}}}}$
