Day 6: Ratio and Proportion

Hello frnz,

Happy Navmi!!! today we will learn about Ratio and Proportion....

:- The ratio of number a to b is known as a/b (if b is not equal to 0).
For eg. Ratio of 2 to 3 is 2/3.


:- 2/3 can be written as 2 to 3 or 2:3. ratio of 4 to 6 is 4/6 and reduced form is 2/3.
So Ratio of 4 to 6 = Ratio of 2 to 3.


:- In ratio, ordered is important means ratio of 2 to 3 is not equivalent to ratio of 3 to 2.

:- Proportion: A proportion is a statement that two ratios are equal.
For eg. 2/3 = 4/6

:- Suppose in given four values of proportion, One is unknown Let's
2/3 = n/6, to solve it, we will cross multiply and get the value of n.

i.e. 2*6 = n*3 (Cross Multiplication)
12 = 3n So n = 4;





Okie guys, Keep practice On.....
