Question 480214

Anita is painting a wall in her room. 

In the morninig, she painted {{{4/18}}} of the wall. 


In the afternoon she painted {{{5/18}}} of the wall. 


 she painted altogether  {{{4/18+5/18}}} of the wall which is {{{(4+5)/18=9/18}}}


now, you can simplify by dividing nominator and denominator by {{{9}}}

{{{9/18=(9/9)/(18/9)=1/2}}}.......... she painted altogether {{{1/2}}} of the wall
