Supports 2, 3, or more parts.
Allocated Distribution
Share 1 (2 parts - 40%) 200.00
Share 2 (3 parts - 60%) 300.00
Visual Share:
200
300
Step-by-Step Breakdown:
  1. Sum all ratio parts: 2 + 3 = 5 total parts.
  2. Calculate the value of one single part: 500 ÷ 5 = 100 per part.
  3. Multiply each ratio part by single part value:
  4. • Share 1: 2 × 100 = 200.00 (40.00%).
  5. • Share 2: 3 × 100 = 300.00 (60.00%).
  6. Verify total sum: 200.00 + 300.00 = 500.00.

How to Divide Any Total by a Ratio

Dividing a sum according to a ratio requires 3 simple steps:

  1. Add the ratio terms: Add all parts of the ratio together to determine the total number of proportional units.
  2. Find the unit value: Divide the total amount by the sum of parts. This gives the value of exactly 1 share.
  3. Multiply by each term: Multiply each individual ratio term by the unit value to find each party's exact allocated share.
