Let x be the number in the first part.
Let y be the number in the second part.
Let z be the number in the third part.
We know that
x + y + z = 243
Then “half of the first part, a third of the second part, and a fourth of the third part are all equal” means
x/2 = y/3 = z/4
Let's look at just one variable. We know that
x = (2/3)y
And
z = (4/3)y
So
(2/3)y + y + (4/3)y = 243
3y = 243
y = 81
Then
x = (2/3)(81)
x = 54
And
z = (4/3)(81)
z = 108
x, y, and z are our sections.
