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