问题描述：
1994又1992分之1乘以1993分之1992
答
(1994+1/1992)*(1992/1993)
=1994*(1992/1993)+(1/1992)*(1992/1993)
=(1993+1)*(1992/1993)+1/1993
=1993*(1992/1993)+1*(1992/1993)+1/1993
=1992+1992/1993+1/1993
=1992+(1992+1)/1993
=1992+1
=1993
答
(1994+1/1992)*(1992/1993)
=(1993+1993/1992)*(1992/1993)
=1993*1992/1993+1
=1992+1
=1993
