What do directly proportional and inversely proportional mean?
Directly proportional variables are those in which if one variable increases, the other also increases. Inversely proportional variables are those in which one variable decreases with the increase in another variable and one variable increases with the decrease in another variable. It is opposite to direct proportion.
Why is inversely proportional a curve?
When two quantities are in inverse proportion, as one increases the other decreases. When we graph this relationship we get a curved graph.
What is inversely proportionality?
Two quantities are said to be inversely proportional when one quantity is in direct proportion to the reciprocal of others. Two variables are called inversely proportional, if and only if the variables are directly proportional to the reciprocal of each other.
How do you find the value of K in inverse proportion?
Method 2) We also know that in an inverse proportion, equation x + y = k becomes x = k/y. So in order to find the value of k, we can use the known values to find the unknown ones with the help of the above. You can also use an inversely proportional formula to solve the sums.

What is an example of inverse proportion in economics?
What is an example of an inverse proportion? As we know, inverse proportion occurs when a decrease in one quantity or variable causes an increase in another quantity or variable. For example, a reduction of workers’ number increases the number of days to complete the building’s construction.
