Answer 2

Answer:

$\red { Required \: number}\green {= \frac{10}{7}}$

Step-by-step explanation:

$Let \: number \: should \:be \: added \:to \\\frac{-3}{7} \: is \: x$

/* According to the problem given,

$\frac{-3}{7} + x = 1$

$Add\: \frac{3}{7} \:both\: sides \: of \: equation,\\we\:get$

$\implies \frac{-3}{7} + x + \frac{3}{7}= 1 +\frac{3}{7}$

$\implies x = \frac{7 + 3}{7}\\= \frac{10}{7}$

Therefore.,

$\red { Required \: number}\green {= \frac{10}{7}}$
