Ratio and Proportion

What is a ratio?
Comparison of two or more quantities of the same kind by division
Ex- Ratio of Boys to Girls 20:10
Ex- Ratio between 250gm and 2kg
Ratio between 5 minutes and 30 secs

Few points about ratio-
Expressed in simplest term
Order of terms is important

Ratio exist only between quantities of same kind
and they should have the same units

Types of ratio-
Inverse ratio
Compound ratio
Duplicate ratio
Triplicate ratio
Sub Duplicate ratio
Sub Triplicate ratio
Continued ratio

Inverse Ratio
Inverse ratio of a:b is b:a
One ratio is the inverse of another if their product is 1

Compound Ratio
Compound ratio of a:b and c:d is ac:bd

Duplicate ratio
A ratio compounded to itself is duplicate ratio.Thus duplicate ratio of a:b is a2:b2

Triplicate ratio
A ratio compounded to itself two time is triplicate ratio.Thus triplicate ratio of a:b is a3:b3

Sub Duplicate ratio- Square root
If a:b is duplicate ratio of c:d then c:d is sub-duplicate ratio of a:b
Find sub-duplicate ratio of

Continued Ratio
Ratio which are expressed in more than 2 quantities
