Question 4 Rational Numbers Exercise 4C

(-5/11) and (7/-11)

Answer:

Solution:-

First, we write each of the given numbers with a positive denominator.

(7/-11) = [(7× (-1))/ (-11×-1)]

= (-7/11)

Then,

(-5/11)+ (-7/11)

We have:

= [(-5 + (-7))/11] … [∵ denominator is same in both the rational numbers]

= [(-5-7)/11)

= (-12/11)
