a) 32/101 + 352/1111 - 3232/10201 = 32/101 + 32/101 - 32/101 =  32/101

b) 17/104 + 187/1144 - 1717/10504 = 17/104 + 17/104 - 17/104 = 17/104

c) 17/18 - 1717/1818 + 171717/181818 - 17171717/18181818 = 17/18 - 17/18 + 17/18 - 17/18 = 0

d) 24/25 + 264/275 - 2424/2525 - 2664/2775 = 24/25 + 24/25 - 24/25 - 24/25 = 0
