Work: Calculate the value of equation 1/12+1/20+1/30+1/42+1/56+1/72+1/90 .
Question type: Mathematical calculation
Solution:
1/12+1/20+1/30+1/42+1/56+1/72+1/90
=0.083333+1/20+1/30+1/42+1/56+1/72+1/90
=0.083333+0.05+1/30+1/42+1/56+1/72+1/90
=0.083333+0.05+0.033333+1/42+1/56+1/72+1/90
=0.083333+0.05+0.033333+0.02381+1/56+1/72+1/90
=0.083333+0.05+0.033333+0.02381+0.017857+1/72+1/90
=0.083333+0.05+0.033333+0.02381+0.017857+0.013889+1/90
=0.083333+0.05+0.033333+0.02381+0.017857+0.013889+0.011111
=0.133333+0.033333+0.02381+0.017857+0.013889+0.011111
=0.166666+0.02381+0.017857+0.013889+0.011111
=0.190476+0.017857+0.013889+0.011111
=0.208333+0.013889+0.011111
=0.222222+0.011111
=0.233333
Answer:1/12+1/20+1/30+1/42+1/56+1/72+1/90=0.233333
