Explanation:

 

 

Ratio

 

In mathematics, a ratio is a relationship between two numbers of the same kind (i.e., objects, persons, students, spoonfuls, units of whatever identical dimension), usually expressed as "a to b" or a:b, sometimes expressed arithmetically as a dimensionless quotient of the two which explicitly indicates how many times the first number contains the second (not necessarily an integer).

 

Notation and terminology

The ratio of numbers A and B can be expressed as:

  •   the ratio of A to B

  •   A is to B

  •   A:B

  •   A rational number which is the quotient of A divided by B (Our solved example in mathguru.com uses this concept)

The numbers A and B are sometimes called terms with A being the antecedent and B being the consequent.
