Objective: Learn how to add and subtract rational numbers
A ratio is a comparison of two numbers, a and b, that can be written as a
fraction a .
b
A rational number is any number that can be written as a ratio , wa here
b
a and b are integers, and b is not 0. Numbers, 0.7, 3, 4.75, and 0.85, can
be expressed as ratios in fraction form.
Therefore, all the numbers above are rational numbers.
Rational numbers can be classified as shown below.
