Question 85923
Question:


 {{{ -9/2 + 3/4 }}}


Here the denominators are different....

So at first convert make the denominators same...



Here Least Common Divisor(LCM) of 2 and 4 is 4


==> {{{ (-9/2) * (4/4)}}}


==>  {{{ (-9/1) * (2/4)}}}



==>  {{{ (-9*2)/4}}}



==> {{{-18/4}}}


Now, {{{ (3/4 )* (4/4)}}}



==> {{{3/4}}}



that is ....


 {{{ -9/2 + 3/4 }}} = {{{(-18/4) + (3/4)}}}




==> {{{ (-18+3)/4}}}




==> {{{ -15/4}}}





Hope you found the explanation useful.


Regards.
