Indirect proportion (inverse proportion) is a relationship between two quantities where as one quantity increases, the other quantity decreases and vice-versa. For example, it takes 1 worker 9 hours to dig a hole.
A direct and inverse proportion are used to show how the quantities and amount are related to each other. They are also mentioned as directly proportional or inversely proportional. The symbol used to denote the proportionality is ‘ ∝ ‘.
Inversely Proportional: when one value decreases at the same rate that the other increases. Example: speed and travel time Speed and travel time are Inversely Proportional because the faster we go the shorter the time.
By definition, inverse (or indirect) proportion occurs when a decrease in one quantity or variable causes an increase by the same factor in another quantity or variable. If we continue operating with the symbols of direct proportion, we can express an inverse proportion as. a:b = d:c. or. a b = d c.
In math, an inverse proportion is when an increase in one quantity results in a decrease in another quantity. This video will show how to solve an inverse proportion math problem. Example : The pressure in a piston is 2.0 atm at 25°C and the volume is 4.0L.
Indirect Proportion. An inverse variation occurs if one of the variables increases or decreases and the other variable decreases or increases. It can be read as “varies inversely” and “inverse proportion”. Inverse variation exists if the relationship exists between the two variables whose product is constant (k).
