脱式计算．（能简算的要简算）

7.6×2.4-0.04	32×12.5×2.5
3.572÷0.47×28	8.25×0.63+0.37×8.25
6.21÷0.69÷0.45	47.04÷0.14+21.3．

Answer 1

（1）7.6×2.4-0.04
=18.24-0.04
=18.2   

（2）32×12.5×2.5
=8×4×12.5×2.5
=（8×12.5）×（2.5×4）
=100×10
=1000  

（3）3.572÷0.47×28
=7.6×28
=212.8   

（4）8.25×0.63+0.37×8.25
=8.25×（0.63+0.37）
=8.25×1
=8.25

（5）6.21÷0.69÷0.45
=9÷0.45
=20    

（6）47.04÷0.14+21.3
=336+21.3
=357.3
