1600÷25×3.5简便运算 解:运用凑整法 原式=1600x4÷(25x4)x3.5 =6400÷100x3.5 =64x3.5 =64x(3+0.5) =64x3+64x0.5 =192+32 =224

1600=16*100 100/4=4 1600/25=64 480=40*12 36=12*3 480/36=40/3

=16x100/25=16x4=64

1600÷25 =16×100÷25 =16×(100÷25) =16×4 =64

1600除以4×16的商简便运算 1600÷(4*16) =1600÷16÷4 =100÷4 =25

1600÷(4×8) =1600÷4÷8 =400÷8 =50

1600x(1+20℅)+75 =1600+320+75 =1995

1600÷25=(1600×4)÷(25×4)=6400÷100=64
