[1/1 Formula]
Work: Calculate the value of equation (1+1/2+1/3+1/4)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4) .
Question type: Mathematical calculation
Solution:
(1+1/2+1/3+1/4)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)
=2.083333*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)
=2.083333*1.283333-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)
=2.083333*1.283333-2.283333*(1/2+1/3+1/4)
=2.083333*1.283333-2.283333*1.083333
=2.67361-2.283333*1.083333
=2.67361-2.47361
=0.2
Answer:(1+1/2+1/3+1/4)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)=0.2
