Answer 1

1、6.3×10.1=6.3×10+6.3×0.1=63.63
2、3.25-0.84-0.16=3.25-(0.84+0.16)=2.25
3、(3.2+0.128)÷0.8=3.2×5/4+0.128×5/4=4+0.16=4.16
4、6.3÷0.21=6.3÷0.7÷0.3=30

Answer 2

6.3×10.1
=6.3×10+6.3×0.1
=63+0.63
=63.63

3.25-0.84-0.16
=3.25-(0.84+0.16)
=3.25-1
=2.25

Answer 3

(6+0.3)×(10+0.1) 3.25-(0.84+0.16)

3.2/0.8+0.128/0.8 6.3/2.1/10
呵呵```看清楚咯 掺了``下面又来了个高手``我们一定没得采用咯

Answer 4

(6+0.3)*(10+0.1)
3.25-(0.84+0.16)
3.2/0.8+0.128/0.8
6.3/2.1/10

Answer 5

（6+0.3)*(10+0.1)
3.25-(0.84+0.16)
3.2/0.8+0.128/0.8
6.3/2.1/10
