45x0.625—0.625 56x62.5怎么简算

45x0.625—0.625 56x62.5怎么简算
=45*0.625-0.625+5600*0.625
=（45-1+5600）*0.625
=3527.5
如果题目修改为45x0.625-0.625+0.56x62.5
=45*0.625-0.625+56*0.625
=（45-1+56）*0.625
=100*0.625
=62.5

1. 45x0.625-0.625 = 0.625×(40+4) = 6.25×4 + 0.625×4 = 25+2.5 = 27.5
2. 56x62.5 = 7×8×25×2.5 = 7×100×5 = 3500
3. 45x0.625 - 0.625 + 56x62.5 = 27.5 + 3500 = 3527.5
