share $150 among john, mary and sarah so that each of the two girls recieves twice as much as john express mary's share as a fraction of the amount recieved by john and sarah
--------
mary share:: 2x
sarah share:: 2x
john share::: x
-----
Equation:
2x + 2x + x = 150
5x = 150
x = 30
----
Mary's share: 2x = $60
----
Sarah + John share: 2x+x = 3x = 3*30 = $90
-----
Fraction: 60/90 = 2/3
