Answer:
(a+b) + c = a + (b+c)
[(-9/11) + (-3/5)] +(-9/22) = (-9/11) + [(-3/5) + (-9/22)]
-201/110 = -201/110
L.H.S = R.H.S
Hence, verified.
Step-by-step explanation:
(a+b) + c = a + (b+c)
a = -9/11
b = 3/-5 = -3/5
c = -9/22
(a+b) + c = a + (b+c)
[(-9/11) + (-3/5)] +(-9/22) = (-9/11) + [(-3/5) + (-9/22)]
[(-9×5/11×5) + (-3×11/5×11)] +(-9/22) = (-9/11) + [(-3×22/5×22) + (-9×5/22×5)]
[(-45/55) + (-33/55)] +(-9/22) = (-9/11) + [(-66/110) + (-45/110)]
[-45/55 - 33/55] - 9/22 = (-9/11) + [-66/110 - 45/110]
-78/55 - 9/22 = -9/11 - 111/110
-78×2/55×2 -9×5/22×5 = -9×10/11×10 -111×1/110×1
-156/110 - 45/110 = -90/110 - 111/110
-201/110 = -201/110
L.H.S = R.H.S
Hence, verified.
