Ratio and Proportion is basically comparison of two similar quantities. Ratio is denoted by the ':'.
For example, the length and breadth of a rectangle is 50 cm and 30 cm. So we can say that the ratio of length and breadth is 5:3.
 
If two ratios are equal then we give them the name of proportion.
For eg:
If straight a over straight b equals straight c over straight d , then we can say that a,b,c,d are in proportion.
 
Algebra is a branch of mathematics, which deals with study of symbols and rules for manipulating the symbols. 
For example,
a + 10 = 20
a = 20 - 10 [In this step, the number 10 is manipulated to bring it to the right hand side]
a = 10
