Question

Exanples for inverse proportion

Answer 1

Answer:

example for inverse proportion

If one value is inversely proportional to another then it is written using the proportionality symbol  in a different way. Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.

The statement ‘b is inversely proportional to m’ is written:



Equations involving inverse proportions can be used to calculate other values.

Using:  (so  is inversely proportional to ).

If  then find .





Similarly, if , find .





Inverse proportion - Higher

Proportionality can be used to set up an equation.

There are four steps to do this:

write the proportional relationship

convert to an equation using a constant of proportionality

use given information to find the constant of proportionality

substitute the constant of proportionality into the equation

Example

If  is inversely proportional to w and when , , then form an equation relating to .





 so 



This equation can be used to calculate new values of  and .

If  then find .





Similarly, if , find .





Answer 2

Step-by-step explanation:

• more workers in the job would reduce the time to complete work
• if u travel slowly the time taken will increase
• more people sharing amount each person will get less money
• 12 people complete the work in 4 days 3 days was taken by 16 workers
