A rational numbers is any numbers that can be written in the form where a
and b are integers and b≠ 0
For examples : -2 , 0 , 9 , 0.3 ,5 1 can be written in the form as : −2 , 0 , 9 , 3 11
2 1 1 1 10 2
Absolute value :
The absolute value of a rational numbers is its distance from zero . since distance is
positive ,or zero .
Then the absolute value of either a positive or a negative rational numbers is
positive .
|5| = 5 and |−5| = 5
Notes : |5| = |−5| because both are 5 units from zero .
