Work with ratios. Mode 'simplify': reduce a ratio a : b to its lowest terms, and give the 1 : n form and the decimal a / b. Mode 'solve': find the missing value x in the equivalent ratio a : b = c : x using cross multiplication. All inputs must be positive. Source: https://hopi.co.uk/ratio-calculator/
