➤ Answer :-

\dashrightarrow \sf \frac{7}{10}  + 8  \frac{2}{5}  -  \frac{11}{2}  \\

\dashrightarrow \sf \frac{7}{10}  +  \frac{42}{5}  -  \frac{11}{2}  \\

LCM of 10,5 and 2 is 10.

\dashrightarrow \sf \frac{7}{10}  +  \frac{42 \times 2}{5 \times 2}  -  \frac{11 \times 5}{2 \times 5}  \\

\dashrightarrow \sf \frac{7}{10}  +  \frac{84}{10}  -  \frac{55}{10}  =  \frac{7 + 84 - 55}{10}  \\

\dashrightarrow \sf \frac{91 - 55}{10}  \\

\dashrightarrow \sf \frac{36}{10}  = 3  \frac{6}{10}  \\

\Huge\thereforeThe answer is  \sf 3 \frac{6}{10} \\
