Questions about this tool
How do I split 1000 in the ratio 2:3?
The parts add up to 5, so the first share is 1000 × 2 ÷ 5 = 400 and the second is 600.
Can the parts be decimals like 1.5:2.5?
Yes. Only the proportion between the parts matters, not whether they are whole numbers.
How do I split profit by each partner’s capital?
Enter each partner’s capital as their part, and you get each partner’s share of the profit.
