1. How do you decide which of two numbers is greater when a. both numbers are positive? b. both numbers are negative? c. one number is positive and one number is negative?

Solution

Solution of question (1).

Part(a) : Here we plot both the numbers on the number line that will be in the right side of value 0 on it that is in the very middle of the number line and the number that is close to value 0 there will be g reater .

===============================================================================

Part(b) : Here we plot both negative numbers on the number line that will be in the left side of value 0 on it that is

in the very middle of the number line and the number that is again close to value 0 there will be greater.

==============================================================================

Part(c) : And surely it is even a universal truth that in two positive and negative numbers, positive number is always greater so there no need to use number line here to get greater number as positive number is already greater.
