Final answer:
To divide ₵810,000 among Sarah, John, and Monica in a 4:3:2 ratio, you can follow these steps: 1) Find the total number of parts, 2) Divide the total amount of money by the total number of parts, 3) Multiply the value of one part by the ratio to find each person's share.
Step-by-step explanation:
To divide ₵810,000 among Sarah, John, and Monica in a 4:3:2 ratio, first find the total number of parts: 4 + 3 + 2 = 9 parts.
Next, divide the total amount of money by the total number of parts to find the value of one part: ₵810,000 ÷ 9 = ₵90,000.
Finally, multiply the value of one part by the ratio to find each person's share:
- Sarah: ₵90,000 × 4 = ₵360,000
- John: ₵90,000 × 3 = ₵270,000
- Monica: ₵90,000 × 2 = ₵180,000
