Four beneficiaries are to divide an estate of \( \$ 189,000 \) in the ratio \( \frac{1}{3}: \frac{1}{4}: \frac{3}{8}: \frac{1}{24} \). How much should each receive?

D, E, and F own a business jointly and share profits and losses in the same portion as their investments. How much of a profit of \( \$ 4500 \) will each receive if their investments are \( \$ 4000, \$ 6000 \), and \( \$ 5000 \) respectively? D will receive \( \$ 1200 \). (Simplify your answer.) E will receive \( \$ 1800 \). (Simplify your answer.) F will receive \( \$ \square \). (Simplify your answer.)
