Answer 1

$\\ \pink{{\hspace{0 pt}\above 2.2pt}\boldsymbol{\mathsf{ P= \frac{2}{5} + 2 + \frac{1}{4} - \frac{3}{8} = \frac{91}{40} }}{\hspace{0pt}\above 2.2pt}}$

$\\ \pink{{\hspace{0 pt}\above 2.2pt}\boldsymbol{\mathsf{ Q = \frac{1}{2} - \frac{3}{4} + \frac{4}{5} + 1 = \frac{31}{20} }}{\hspace{0pt}\above 2.2pt}}$

$\\ \pink{{\hspace{0 pt}\above 2.2pt}\boldsymbol{\mathsf{ \frac{91}{40} + \frac{31}{20} = \frac{153}{40} = 3.825 }}{\hspace{0pt}\above 2.2pt}}$
