Question

Using suitable re- arrangements, find the sum 5/9+(-3/11)+7/9+(-7/11).​

Answer 1

Answer:

Given, 4/3 + 3/5 + -2/3 - 11/5

= 4/3 + -2/3 + 3/5 - 11/5

= (4/3 + -2/3) + (3/5 - 11/5)

= (4/3 - 2/3) + (3/5 - 11/5)

= (4 - 2)/3 + (3 - 11)/5

= 2/3 + (-8/5)

= 2/3 - 8/5

= (2*5 - 8*3)/15

= (10 - 24)/15

= -14/15

So, 4/3 + 3/5 + -2/3 - 11/5 = -14/15
