Add the numbers : `(-11)/(13)+ 9/(13)`

Add the rational number: :(6)/(13) and (-9)/(13)

Add the rational number : 6/(13)\ a n d\ (-9)/(13)

Add the following rational numbers: (-8)/(11)\ a n d(-4)/(11) (ii) 6/(13)\ a n d\ (-9)/(13)

Add without using number line : (-13) + (+18)

Add without using number line: (-13)+(+18)

Let's add the following- (vi) (+13) + (-13)

Add the following rational numbers: (i) (-8)/(11)\ a n d(-4)/(11) (ii) 6/(13)\ a n d\ (-9)/(13)

Add the product of (-13) and (-17) to the quotient of (-187) and 11.

Subtract the first rational number from the second in each of the following : (-2)/(11),(-9)/(11) (ii) (11)/(13),(-4)/(13)
