Question 85528
An ash and an oak grew together side by side in the forest.  Over the years the ash grew to be one and a quarter times as high as the oak.  One day the woodcutter came along and lopped 3 meters off the height of both trees and now the ash is one and a third times the height of the oak.  How high was the ash originally
-----------------
"One Day" DATA:
Ht. of oak = x ft. ; Ht of ash = (5/4)x ft
------------
"After Cut" DATA:
Ht of oak = x-3 ft ; Ht of ash = (5/4)x-3
----------------
EQUATION:
ash = (4/3)oak
(5/4)x-3 = (4/3)(x-3)
Multiply both sides by 12 to get rid of the denominators:
15x-36 = 16x-48
x=12 ft (original ht of oak)
(5/4)x = (5/4)12 = 15 ft. (original ht of ash)
