   Giải thích các bước giải:

   S = 1 – 17/6 + 31/12 – 49/20 + 71/30 – 97/42 + 127/56 – 161/72 + 199/90

   s= (1- 17/6) + (31/12 – 49/20) + (71/30 – 97/42) + (127/56 – 161/72) + 199/90

   s= -11/6+2/15+2/35+2/63+199/90

   s=  3/5

2. S = 1 – 17/6 + 31/12 – 49/20 + 71/30 – 97/42 + 127/56 – 161/72 + 199/90

   S= (1- 17/6) + (31/12 – 49/20) + (71/30 – 97/42) + (127/56 – 161/72) + 199/90

   S= -11/6+2/15+2/35+2/63+199/90

   S=  3/5
