How to solve Proportions

Introduction:

A proportion means comparison or equality among two ratios. We can also say that it is used to compare two ratios or make an equivalent fraction. In proportions we have two groups, one is extreme and the other is mean. Extreme means the first and the last number and the mean is the second and the third number of a proportion of four parts.

Solving Proportions:

There are different ways of solving proportions
By doing equivalent fractions:
This works when the denominator and numerator of one fraction is multiple of the another one
By simplifying:
Numerator and denominator of one fraction is not a multiple of another one.
Cross multiplication:
It means multiplying the numerator of the first fraction to the denominator of the second fraction equals to the denominator of the first fraction to the numerator of the second fraction.
1.Solving proportions by finding equivalent fractions
`(4)/8=10/n`
so, to find the equivalent fractions we need to multiply and divide the numerator and the denominator by the same number. To solve this multiply the numerator by 8 to get 32 and the denominator by 5.
`(4xx8)/(8xx8)=10/n`
`(32)/64=10/n`
so, n=20
