Split by ratio

T = 100 split in the ratio 2 : 3 : 5: each part is T × w ÷ Σw. Whatever you do to the weights, the parts always add back up to T.

You can change the numbers right here, but changes made here are not saved. To keep what you build, use “Open in CalcAnyway” and edit there.

Try moving it

Change w₁ from 2 to 4 — the parts rearrange to 33.3 / 25 / 41.7, still summing to 100.
Set T to 1 — the parts become 0.2 / 0.3 / 0.5. A ratio is just “the split when the whole is 1”.
