简便运算 1、(4.48-4.48÷1.2)÷0.2 2、45.2÷1.13×40.1 3、16.8÷(0.5+3.7)×0.04
简便运算:
1、(4.48-4.48÷1.2)÷0.2
=4.48*(1-1.2)/0.2
=-4.48*1
=-4.48
2、45.2÷1.13×40.1
=40*40.1
=1604
3、16.8÷(0.5+3.7)×0.04
=16.8/4.2*0.04
=4*0.04
=0.16 .

56/15 1604 4/25

不会

1、(4.48-4.48÷1.2)÷0.2
=4.48*(1-5/6)/0.2
=56/15
2、45.2÷1.13×40.1
=40*40.1
=1604
3、16.8÷(0.5+3.7)×0.04
=16.8/4.2*0.04
=4*0.04
=0.16 .

(4.48-4.48÷1.2)÷0.2
=4.48÷0.2 2-4.48÷1.2÷0.2
45.2÷1.13×40.1
=40*40.1
=1604
16.8÷(0.5+3.7)×0.04
=16.8÷4.2*0.04
=4*0.04
=0.16
