Learn how to solve a proportion right now!
Before learning about how to solve a proportion, it is necessary for you to learn what proportions really are. In their simplest form, proportions are special algebraic equations wherein two ratios are compared with each other, or in which equivalent fractions are made. For those who don’t know, ratios are used to make a comparison in between two separate values. For instance:
1 orange: 3 apples
Through this ratio, we can work out that for every orange, there are three apples.
When you go about solving a proportion, you would actually be stating ratios in the form of fractions in which two separate fractions would be placed alongside each other with cross-multiplications being used to solve the equations. Here’s a proportion examples for you to consider:
The proportion is:
2 : x = 3 : 0 and you basically need to find the unknown value here. For this purpose, you would need to initially convert the ratios in to their basic fractional form, wherein these would be written as:
Now, you may solve the proportion as:
9(2) = x(3)
18 = 3x
6 = x
A look into divine proportion examples
The divine proportion is known by a number of names such as the golden mean, golden section etc. Basically, it is a mathematical formula that is represented by Phi (1.618).
To explain things better, it is believed that two quantities would be in their divine proportion as long as their ratio happens to be equal to the ratio of their sum to their maximum. Here’s basic divine proportion examples to help you understand the concept better:
where the Greek letter phi () is being used in order to signify the golden ratio. Its value is:
A few direct proportion examples
Two variables are believed to be directly proportional where one variable is either divided or multiplied by a number, the same number is used in order to divide or multiply the other variable. Consider these direct proportion examples:
Let us consider that a car is moving at 240 miles in 3 hours. How many miles would it have traveled in 2 hours? Here in, time and distance are two directly proportional values and the output would be:
Simple inverse proportion examples
Two values are considered as being inversely proportional when as soon as one value decreases, the other starts increasing. The best inverse proportion examples are light and distance, considering that the further that you move away from a source of light, the less bright it would be.
