Question 380207
Frank has half as many again as sally who has half again as many again as mary. Altogether they have 209.
how many has each?
---
Let Mary have "x"
Then Sally has "(3/2)x"
And Frank has (3/2)(3/2 x) = (9/4)x
-----------------------------------------
Equation:
x + (3/2)x + (9/4)x = 209
4x + 6x + 9x = 4*209
19x = 4*209
x = 44
(3/2)x = 66
(9/4)x = 99
