Question

verify the following.


(-5/8+9/8)+ 13/18=-5/8+(9/8+13/18)

​

Answer 1

$( \frac{ - 5}{8} + \frac{9}{8} ) + \frac{13}{18} = \frac{-5}{8} + ( \frac{9}{8} + \frac{13}{18} )$

$LHS = :$

$= ( \frac{ - 5 + 9}{8} ) + \frac{13}{18}$

$= \frac{4}{8} + \frac{13}{18}$

$= \frac{36 + 52}{72}$

$= \frac{88}{72}$

$RHS =:$

$= \frac{ - 5}{8} + ( \frac{9}{8} + \frac{13}{18} )$

$= \frac{ - 5}{8} + ( \frac{81 + 52}{72} )$

$= \frac{ - 5}{8} + \frac{133}{72}$

$= \frac{ - 45 + 133}{72}$

$= \frac{88}{72}$

$LHS \: = \: RHS$

$Hence \: , \: Verified$
