WebThis concept is based upon the Inverse Property of Multiplication that says: Any number multiplied by its reciprocal = 1. For example: 12/5 * 5/12 = 60/60 = 1. If you find it easier, you can do cross multiplication. This is where you multiply along each diagonal of the proportion. 4/z = 12/5. 12 (z) = 4 (5) 12z = 20. WebInverse Proportionality – The Basics If two quantities are inversely proportional, then as one increases the other decreases at the same rate (proportionally), e.g. as one doubles, the other one halves.
