Question

verify that (a+b)+c=a+(b+c)

Answer:

L.H.S. R.H.S.

=>(7/-11 + (-2/5)) + -3/22 =7/-11 + (-2/5 + ( -3/22))

=>(-7/11 - 2/5) -3/22 =-7/11 + (-2/5 - 3/22)

=>(-35/55 -22/55)-3/22 = -7/11 + (-44/110 - 15/ 110)

=>-57/55 -3/22 = -7/11 - 59/110

=>-114/110 - 15/110 = -70/110 - 59/110

=>-129/110 = -129/110

L.H.S = R.H.S.

Step-by-step explanation:

L.H.S. R.H.S.

=>(7/-11 + (-2/5)) + -3/22 =7/-11 + (-2/5 + ( -3/22))

=>(-7/11 - 2/5) -3/22 =-7/11 + (-2/5 - 3/22)

=>(-35/55 -22/55)-3/22 = -7/11 + (-44/110 - 15/ 110)

=>-57/55 -3/22 = -7/11 - 59/110

=>-114/110 - 15/110 = -70/110 - 59/110

=>-129/110 = -129/110

L.H.S = R.H.S.
