Tip: First share saturates at T as a grows much larger than b; equal a and b splits T evenly.

Frequently asked questions

How do I split a total in the ratio a:b?

First person gets a/(a+b) of the total and second gets b/(a+b). For total 240 split 3:5, the first share is 3/8 * 240 = 90 and the second is 5/8 * 240 = 150. The lab does this division automatically.

How do I use the ratio splitter lab?

Slide total T and the two share numbers a and b. The lab shows how T splits into a*T/(a+b) and b*T/(a+b). Try T = 500 with a:b = 2:3 to see Rs 200 and Rs 300.

How are ratios used to share money among siblings or partners?

If two brothers invest Rs 30000 and Rs 20000 in a kirana shop, profit splits in the ratio 3:2. A profit of Rs 10000 splits as Rs 6000 and Rs 4000. The lab handles this kind of business calculation for any totals up to 1000.

Equal split vs ratio split: when do I use each?

Equal split is just T divided by the number of people. Ratio split is used when contributions are unequal, like in business partnerships or hostel rent based on room size. The lab covers the ratio case; for equal split just set a = b in the lab and see both shares match.
