question_answer 1)

(a) Write four negative integers greater than ?20. (b) Write four negative integers less than ?10.

Answer:

(a) Negative integers greater than ?20 on number line are shown as below When we move on number line to the right, then the value of integer increases. So, it is clear from figure that when we move right of ?20, we will get integers greater than ?20. So, four negative integers greater than ?20 are ?19, ?18, ?17 and ?16. (b) Negative integers which are less than ?10 on number line are shown as below When we move on number line to the left, then the value of integer decreases. So, it is clear from the above figure that when we move left of ?10, we will get integers less than of ?10. So, four negative integers less than ?10 are ?11, ?12, ?13 and ?14.
