Answer 1

$\frac{5}{6 3} - (\frac{- 6}{2 1}) = \frac{5 \times 1}{6 3 \times 1} - (\frac{- 6}{2 1}) = \frac{5 \times 1}{6 3 \times 1} - (\frac{- 6 \times 3}{2 1 \times 3}) = \frac{5}{6 3} - \frac{- 1 8}{6 3} = \frac{5 - ( - 1 8 )}{6 3} = \frac{5 + 1 8}{6 3} = \frac{2 3}{6 3}$
L.C.M of $63$ and $21$ is $63$

Answer 2

\frac{5}{6 3} - (\frac{- 6}{2 1}) = \frac{5 \times 1}{6 3 \times 1} - (\frac{- 6}{2 1}) = \frac{5 \times 1}{6 3 \times 1} - (\frac{- 6 \times 3}{2 1 \times 3}) = \frac{5}{6 3} - \frac{- 1 8}{6 3} = \frac{5 - ( - 1 8 )}{6 3} = \frac{5 + 1 8}{6 3} = \frac{2 3}{6 3}

L.C.M of

63

and

21

is

63
