What is Ratio?

A Ratio is a comparison of the sizes of two or more quantities of the same kind by division.

If a and b are two quantities of the same kind (in same units), then the fraction a/b is called the ratio of a to b.

What is an Inverse Ratio?

One Ratio is the inverse of another if their product is 1. Thus a:b is the inverse of b: a and vice versa.

What is Proportion?

An equality of two ratios is called a proportion.

For quantities a,b,c,d are said to be in proportion if a:b= c:d

Properties of Proportion-

1. Alternendo

If a : b = c : d, then a : c = b : d.

ab = cd

Multiply both sides by bc ; ab x bc = cd x bc

ac = bd

a : c = b : d

2. Componendo

If a : b = c : d, then a + b : b = c + d : d

ab = cd

Adding 1 to both sides, we get

ab + 1 = cd + 1

a+bb = c+dd

⇒ a + b : b = c + d : d

3. Dividendo

If a : b = c : d then a - b : b = c - d : d

ab = cd

Subtracting 1 from both sides, we get

ab - 1 = cd - 1

a−bb = c−dd

⇒ a - b : b = c - d : d

4. Componendo and Dividendo-

If a : b = c : d then a + b : a - b :: c + d : c - d.

a : b = c : d

a + b : b = c + d : d by componendo

a - b : b = c - d : d by dividendo

Dividing,

a+bb ÷ a−bb = c+dd ÷ c−dd

a+bb x ba−b = c+dd x dc−d

a+ba−b = c+dc−d

⇒ a + b : a - b = c + d : c - d

One to One Correspondence and Equivalent Sets Suppose the members of the family are dinning and plates are prepared on the table then there is a One to one correspondence between the set of family members and the plates prepared. We will indicate this correspondence by the symbol If each element of a set A is associated with one and only one element of a set B and each element of B is associated with one and only one element of set A, then the sets A and B are said to be in one to one correspondence. If both the sets are finite and if they are in one to one correspondence, it is obvious that they have the same number of elements. If two sets have the same number of elements, they are said to be equivalent sets. Using symbol, we write A B. Between two equivalent sets, a one to one corr...
