Let x be the number.

 \frac{2}{3}x =  \frac{1}{4} x + 20

LCD: 12

Multiply each term by LCD 12:
     
     (12)( \frac{2}{3} x) = (12) \frac{1}{4} x + 20 (12)
 
     8x = 3x + 240
 
     8x - 3x = 240

     5x/5 = 240/5
 
     x = 48

ANSWER: The number is 48.

Check:
   2/3 (48) = 1/4(48) + 20
   32 = 12 + 20
   32 = 32   (True)
