-1
0​

Answer 1

Answer:

answer for the given problem is given

Answer 2

$\underline {\pink{ Existence \:of \:a \:additive \: identity:}}$

$' 0 ' \: is \: a \: rational \: number \:such \:that$

$the \:sum \:of \:any \: rational \: number \:and$

$' 0 ' \:is \: the \: rational \: number \:itself .$

$Thus, \boxed{ \blue{\frac{a}{b} +0= 0 + \frac{a}{b} = \frac{a}{b} }}$

$\blue{ ( for \: every \: rational \:number \: \frac{a}{b} ) }$

$Here, Given \: number \: [ \frac{a}{b}+ \frac{c}{d} ]$

$\red{ Additive \: identity \: of \: above \: given}$

$\red{ expression } \green { = 0 }$

$\underline{ \red{ Note : }}$

' 0 ' is called the additive identity for rational numbers.
