Question 1141630
.
<pre>
1)  {{{4/9}}} of 36 apps is  16 apps.

    So, Harold had 16 games in his phone initially.



2)  The new proportion is  


        {{{(16+x)/(36+x)}}} = {{{2/3}}},


    which implies  


        3*(16+x) = 2*(36+x)

        48 + 3x = 72 + 2x


        3x - 2x = 72 - 48

         x      = 24.


<U>ANSWER</U>.  Hi downloaded 24 games.
