Let x be the number
thus      3x is the other  #
             1/3x + 1/x =    4/3      / multiply the whole equation by 3x
           3x(1/3x + 1/x)   =    3x*4/3
             1+ 3 =  4x
             4x = 4
             x = 1
             the other # = 3x  = 3

X is three times in x
reciprocal=4/3
4/3=3/4
3/4 divided by three 
=1/4
X=3/4 x=1/4
