Answer 2

$solution$

$let \: required \: number \: be \: x$

$x + \frac{ - 4}{5} = \frac{ - 1}{3}$

$x = \frac{ - 1}{3} - \frac{ - 4}{5}$

LCM of 3 and 5 is 15.

$x = \frac{ - 5 - ( - 12)}{15}$

$x = \frac{ - 5 + 12}{15}$

$x = \frac{7}{15}$

$proof$

$= > \frac{7}{15} + \frac{ - 4}{5}$

LCM of 5 and 15 is 15.

$= > \frac{7 + ( - 12)}{15}$

$= > \frac{ - 5}{15}$

$= > \frac{ - 1}{3}$

hence proved.
