Work: Calculate the value of equation 1/2+1/3+3/5+6/7+7/12+9/20+11/30+13/42 .
Question type: Mathematical calculation
Solution:
1/2+1/3+3/5+6/7+7/12+9/20+11/30+13/42
=0.5+1/3+3/5+6/7+7/12+9/20+11/30+13/42
=0.5+0.333333+3/5+6/7+7/12+9/20+11/30+13/42
=0.5+0.333333+0.6+6/7+7/12+9/20+11/30+13/42
=0.5+0.333333+0.6+0.857143+7/12+9/20+11/30+13/42
=0.5+0.333333+0.6+0.857143+0.583333+9/20+11/30+13/42
=0.5+0.333333+0.6+0.857143+0.583333+0.45+11/30+13/42
=0.5+0.333333+0.6+0.857143+0.583333+0.45+0.366667+13/42
=0.5+0.333333+0.6+0.857143+0.583333+0.45+0.366667+0.309524
=0.833333+0.6+0.857143+0.583333+0.45+0.366667+0.309524
=1.433333+0.857143+0.583333+0.45+0.366667+0.309524
=2.290476+0.583333+0.45+0.366667+0.309524
=2.873809+0.45+0.366667+0.309524
=3.323809+0.366667+0.309524
=3.690476+0.309524
=4
Answer:1/2+1/3+3/5+6/7+7/12+9/20+11/30+13/42=4
