how to represent the rational number line
Answers
Use the following steps to represent 4 / 7 on the number line.
1) Draw a number line.
2) As the number 4 /7 is a positive number so it will be on right side of zero.
3) So after zero mark, 1/ 7 , 2 /7 , 3 / 7, 4 / 7, 5/ 7 , 6/ 7 , ( 7 / 7 = 1).

Example :
Represent -5 / 3 on the number line.
Solution:
__________________________
1) Draw a number line.
2) As the number – 5 / 3 is a negative number so it will be on left of zero. -5/3 can be written in mixed fraction as -1 2/3. So the number lie between -1 and -2.
3) So left side of zero mark, -1 / 3 , - 2 / 3 , ( -3 /3 = -1) , -4 /3 , -5 / 3,
( -6 / 3 = -2 )

3) Between which two numbers 7/3 lie.
Solution :
1) If the given rational no. is in improper form then convert it to mixed fraction.
7/3 = 2 ⅓
The whole number is 2 so the given rational no. lie between 2 and 3.

2) Between which two numbers -13/3 lie.
Solution : If the given rational no. is in improper form then convert it to mixed fraction.
-13/3 = -4 ⅓
The whole number is -4 so the given rational no. lie between -4 and -5.
