Answer 2

$\huge\bold{\mathscr{QUESTION}}$

${\Large{\frac{21}{30}}}+{\Large{\frac{-19}{20}}}$

$\huge\bold{\mathscr{TO\:\:FIND}}$

The sum.

$\huge\bold{\mathscr{SOLUTION}}$

${\Large{\frac{21}{30}}}+{\Large{\frac{-19}{20}}}$

$\implies{\Large{\frac{21}{30}}}-{\Large{\frac{19}{20}}}$

$\implies{\Large{\frac{\{(21×2)-(19×3)\}}{60}}}$

$\implies{\Large{\frac{\{(42)-(57)\}}{60}}}$

$\implies{\Large{\frac{-15}{60}}}$

Divide the numerator and denominator by 15.

$\implies{\Large{\frac{\cancel{-15}}{\cancel{60}}}}$

$\implies{\Large{\frac{-1}{4}}}$

$\huge\bold{\mathscr{HENCE}}$

${\Large{\frac{21}{30}}}+{\Large{\frac{-19}{20}}}={\Large{\frac{-15}{60}}}$

$\huge\bold{\mathscr{THEREFORE}}$

The value of ${\Large{\frac{21}{30}}}+{\Large{\frac{-19}{20}}}$ is ${\Large{\frac{-15}{60}}}$.
