Let x = the amount that two children get
x/2 = amount third child gets
x + x + x/2 = 80,000
5/2 x = 80,000
x = (80000)(2/5)
x = 32,000
$32,000
$32,000
$16,000
That works! hope you understand it.

Solution :
Let X = the amount got by the first 2 grandchildren
X/2 = the amount got by the 3rd grandchild
Let the equation be :
X + X + X/2 = 80,000
get the least common denominator
(2X + 2X + X)/2 = 80,000
transpose 2 by cross multiplying
2X + 2X + X = 160,000
5X = 160,000
X = 160,000/5
X = 32,000
X/2 = 16,000
Check :
X + X + X/2 = 80,000
32,000 + 32,000 + 16,000 = 80,000
80,000 = 80,000

This needs a simple equation really.
Let x be the amount.
$80, 000 = x + x + 1/2x
$80, 000 = 2.5x
x = $32000
The two grandchildren each received $32 000 while the other gets $16 000.

80000/5 SHARES = 16000 PER SHARE
GRAN 1, 2 SHARES = 32000
GRAN 2, 2 SHARES = 32000
GRAN 3, 1 SHARE =16000
_______
TOTAL 80000
16000 IS 1/2 OF 32000 EASY

2x+1/2x=2,5x=80000
80000 /2.5x=32000
x=32000
2x=64000
1/2x=16000
64000+16000= 80000
