Question 86142
One number is 2 times another. If the sum of their reciprocals is 3/20, find the 2 number.
------------------
Let one of the numbers be "x"; The other number is "2x".
EQUATION:
(1/x + 1/(2x)) = 3/20
-----------
The LCM is 20x
Multiply thru by the LCD to get:
------------
20 + 10 = 3x
30 = 3x
x=10
