104/99+104/33+104/11)÷(100/99+100/33+100/11) 19961997×19971996—19961996×19971997
问题描述:
104/99+104/33+104/11)÷(100/99+100/33+100/11) 19961997×19971996—19961996×19971997
答
(104/99+104/33+104/11)÷(100/99+100/33+100/11)
=[104(1/99+1/33+1/11)]÷[100(1/99+1/33+1/11)]
=104÷100
=26/25
=1.04
19961997×19971996—19961996×19971997
=19961997×(19971997-1)-19961996×19971997
=19961997×19971997-19961997-19961996×19971997
=19971997×(19961997-19961996)-19961997
=19971997-19961997
=10000
