请各位高手帮忙解答几道奥数题1、4.25×5.24×1.52×2.51=2、 0.01992乘0.004乘2000分之1怎样用简便方法算,麻烦各位写出详细解题过程
1又25分之13乘2.51+4又4分之1乘5.24=
-(+4.25)化简化简-(+4.25)
(1)原式=4.25×4×5.24/4+1.52/4×4×2.25=17×1.31+0.38×9=20×1.31-3.93+0.38×10-0.38=26.2+3.8-4.31=30-4.31=25.69(2)原式共有998+1项,在前998项中,1-3=-2,5-7=-2……1993-1995=-2,这样差为-2的组有499组故原式=-2×499+1997=1997-2×50
