[1/1 Formula]
    Work: Calculate the value of equation 1/2+1/6+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10 .
    Question type: Mathematical calculation
    Solution:
          1/2+1/6+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10
        =0.5+1/6+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10
        =0.5+0.166667+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10
        =0.5+0.166667+0.083333+1/20+1/30+1/42+1/56+1/72+1/90+1/10
        =0.5+0.166667+0.083333+0.05+1/30+1/42+1/56+1/72+1/90+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+1/42+1/56+1/72+1/90+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+0.02381+1/56+1/72+1/90+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+0.02381+0.017857+1/72+1/90+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+0.02381+0.017857+0.013889+1/90+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+0.02381+0.017857+0.013889+0.011111+1/10
        =0.5+0.166667+0.083333+0.05+0.033333+0.02381+0.017857+0.013889+0.011111+0.1
        =0.666667+0.083333+0.05+0.033333+0.02381+0.017857+0.013889+0.011111+0.1
        =0.75+0.05+0.033333+0.02381+0.017857+0.013889+0.011111+0.1
        =0.8+0.033333+0.02381+0.017857+0.013889+0.011111+0.1
        =0.833333+0.02381+0.017857+0.013889+0.011111+0.1
        =0.857143+0.017857+0.013889+0.011111+0.1
        =0.875+0.013889+0.011111+0.1
        =0.888889+0.011111+0.1
        =0.9+0.1
        =1

    Answer:1/2+1/6+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10=1
