Question

Use a number line to write the following integers in ascending (increasing) order : 

(i) -5, 8, 0, -9, 4, -14 and 12 

(ii) -6, 7, 0, -9, 5 and 9

Answer 1

(i) -5, 8, 0, -9, 4, -14 and 12 

Draw a number line for integers, as shown below, and mark on it all the given integers. 

Clearly, the given integers in the ascending order are : 

-14 < -9 < -5 < 0 < 4 < 8 < 12 

(ii) -6, 7, 0, -9, 5 and 9 

Draw a number line for integers, as shown below, and mark on it all the given integers.

 

Clearly, the given integers in the ascending order are : 

-9 < -6 < 0 < 5 < 7 < 9
