Final answer:
To divide the sum of money among a, b, and c in the ratio 2:3:5, we need to find the total value of the ratio, determine the value of 1 part of the ratio, and calculate the share of each person.
Step-by-step explanation:
To divide the sum of money among a, b, and c in the ratio 2:3:5, we need to find the total value of the ratio. This can be done by adding up the parts of the ratio: 2 + 3 + 5 = 10.
Now, we can determine the value of 1 part of the ratio by dividing the smallest share by its corresponding ratio value: $600 / 2 = $300.
Finally, we can calculate the share of each person by multiplying the value of 1 part by their ratio value. For example, person a's share is 2 * $300 = $600.
