Introduction of algebra ratio and proportion:
Define of algebra ratio:
In mathematics, a ratio expresses the magnitude of quantities relative to each other. Specifically, the ratio of two quantities indicates how many times the first quantity is contained in the second and may be expressed algebraically as their quotient
Define of algebra proportion:
If the two or more Ratio Proportion encompass all of the quantities in a particular situation.

Definition of Algebra Proportion:
The ratio `25/5` may be simplified and written as `5/1`.
`25/5`=`5/1`
An equation that states that two ratios are equal is called an algebra proportion. The preceding algebra proportion may also be written in the form 25:5=5:1.
Concept of algebra proportion:
A proportion is an equation that states that two ratios are equal: `m/n`=`p/q` or m:n=p:q (provided n?0 and q?0)
Each term of proportion is given a special name according to its position in the proportion.
`m/n`=`p/q`
Where
m is first proportional
n is second proportional
p is third proportional
q is fourth proportional
the pair of terms that form the 1st and 4th proportional’s are called as the extremes of a proportion; the 2rd and 3rd proportional of a proportion are called the means of a proportion.
The pair of terms m and p are called as the extremes of the proportion; the pair of terms n and q are referred to as the means of the proportion.
Example for algebra proportional:
Find the first proportional if the remaining terms of a proportion are 1,3 and 9.
Solution:
Let x=first proportional. Then
x/1=3/9
x=`1/3`
x`xx`3=`1/3``xx`3
3x=1
x=`1/3`
The first proportional is `1/3`.
Sometimes we may be able to work with lesser numbers by simplify an arithmetic ratio in the innovative proportion before cross-multiplying.
Algebra is widely used in day to day activities watch out for my forthcoming posts on Degree of Polynomial and What is the Dependent Variable in an Experiment. I am sure they will be helpful.
Definition of Algebra Ratios:
The ration of two numbers a and b(b?0) is the quotient of the numbers. The numbers a and b referred to as the terms of the ratio.
Example problem for algebra ratios:
Example 1:
Solve `25/125`
Solution:
=`1/5` (numerator and denominator are divided by 25)
=`1/5`
Answer is `1/5`or 1:5
Example 2:
Solve`(30/15)``xx``(12/2)`
Solution:
=`(30/15)``xx``(12/2)`
= `360/30`(numerator and denominator are divided by 10)
=`36/3` (numerator and denominator are divided by 3)
=12 or `12/1`
Answer is `12/1` or 12:1
