Question

verify commutative property of addition for the following pairs of rational numbers
9/11and2/13 ​

Answer 1

Answer:

To Verify : Commutative property* of addition for $\frac{9}{11}$ and $\frac{2}{13}$.

*we have to verify that  $\frac{9}{11}$ + $\frac{2}{13}$ =  

$\frac{9}{11}$ + $\frac{2}{13}$ =  $\frac{2}{13}$ +  $\frac{9}{11}$.

LHS = $\frac{9}{11}$ + $\frac{2}{13}$

=  $\frac{117+22}{143}$

= $\frac{139}{143}$

RHS = $\frac{2}{13}$ +  $\frac{9}{11}$

=  $\frac{22+117}{143}$

=  $\frac{139}{143}$  =  LHS        

HENCE, VERIFIED.
