Question

Verify that (a+b) +C=a+(b+C) taking a=-9/11, b=3/-5 and c=-9/22

Answer 1

Answer:

association method of addition

= (9/11+3/-5) + (-9/22)

= LCM OF 11 & 5 IS 55

= (45/55-33/55) + (-9/22)

= 12/55+(-9/22)

= LCM OF 55 AND 22 IS 110

= 24/110 + (-45/110)

= 24-45/110

= -21/110✔

Answer 2

Given:

a= --9/11,b= 3/-5,c= -9/22

Step by Step Explanation:

(Putting the value of a,b and c)

-9/11-3/5+9/22=-9/11-3/5+9/22

Now cancelling all because of same sign on both sides

Therefore we get

0=0
