Answer:
Right
Right
Step-by-step explanation:
In a number line, numbers proceed from the left to the right in ascending order.
Given the two operations
-20 >-21
-19>-20
Since -20 is greater than -21 , -20 is the location to the right of -21.
Also since -19 greater than -20 on the number line -19 is located to the right of -20 on the number line.
In general, numbers greater than are to the right of that number and numbers less than a number are to the left of the number.
