[1/1 Formula]
    Work: Calculate the value of equation 3/5+6/7+5/6+7/12+9/20+11/30+13/42 .
    Question type: Mathematical calculation
    Solution:
          3/5+6/7+5/6+7/12+9/20+11/30+13/42
        =0.6+6/7+5/6+7/12+9/20+11/30+13/42
        =0.6+0.857143+5/6+7/12+9/20+11/30+13/42
        =0.6+0.857143+0.833333+7/12+9/20+11/30+13/42
        =0.6+0.857143+0.833333+0.583333+9/20+11/30+13/42
        =0.6+0.857143+0.833333+0.583333+0.45+11/30+13/42
        =0.6+0.857143+0.833333+0.583333+0.45+0.366667+13/42
        =0.6+0.857143+0.833333+0.583333+0.45+0.366667+0.309524
        =1.457143+0.833333+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:3/5+6/7+5/6+7/12+9/20+11/30+13/42=4
