Concept explainers
To describe: The method of proportion to solve the problem be easier way.
Explanation of Solution
Given: A equation to solve by constant of proporionality.
This is direction or indirect proportion. Using this to solve any factor easy way .
If a quality increase with fixed multiple of constant then it easy to calculate future value.
If the constant of proportion is direct then according to time both quality increase.
For example: If 1 m cloth cost be $5 and to find the cost of 10 m cloth.
This is direct variation problem because as length of cloth increase their price must be increases.
Yes, it matter which method need to use for particular problem.
For direct proportion: If a quality is increase another quantity must be increase.
For indirect proportion: If a quantity increase another quantity must be decrease.
Use different method for different problem because it depends on the data vary.
