Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Hours for subject 1:
totalHours*(weight1/(weight1+weight2)) - Hours for subject 2:
totalHours*(weight2/(weight1+weight2))
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Total study hours available = 10, Subject 1 weight = 3, Subject 2 weight = 2, this calculator returns Hours for subject 1 = 6 hours, Hours for subject 2 = 4 hours.
