Answer:
Step-by-step explanation:
Let Benjamin marble = x
Alvin marble = x - 12
Chloe marble = x/4
Total marble = 42
X + X - 12 + X/4 = 42
2X + X/4 = 42 + 12
2X + X/4 = 54
MULTIPLY EACH TERM BY 4
8X + X = 216
9X = 216
X = 216/9
X = 24
Chloe marble = X/4 = 24/4 = 6

Ok, so basically let's start with a proportion.
x/32 = 11.25/9
Cross multiply:
x * 9 = 32 * 11.25
9x = 32 * 11.25
9x = 360
Solving for variable 'x'.
Divide each side by '9'.
x = 40
I don't know if this is the correct answer, but it was based on my math. I hope this helps!
