[1/2 Formula]
    Work: Calculate the value of equation (17+7/27+27+7/17-11-37/39)/(13+12/17+8+17/27-5-38/39) .
    Question type: Mathematical calculation
    Solution:
          (17+7/27+27+7/17-11-37/39)/(13+12/17+8+17/27-5-38/39)
        =32.722306/(13+12/17+8+17/27-5-38/39)
        =32.722306/16.361153
        =2
    Answer:(17+7/27+27+7/17-11-37/39)/(13+12/17+8+17/27-5-38/39)=2
[2/2 Formula]
    Work: Calculate the value of equation 1+1/(1+2)+1/(1+2+3)+1/(1+2+3+4) .
    Question type: Mathematical calculation
    Solution:
          1+1/(1+2)+1/(1+2+3)+1/(1+2+3+4)
        =1+1/3+1/(1+2+3)+1/(1+2+3+4)
        =1+1/3+1/6+1/(1+2+3+4)
        =1+1/3+1/6+1/10
        =1+0.333333+1/6+1/10
        =1+0.333333+0.166667+1/10
        =1+0.333333+0.166667+0.1
        =1.333333+0.166667+0.1
        =1.5+0.1
        =1.6
    Answer:1+1/(1+2)+1/(1+2+3)+1/(1+2+3+4)=1.6
