Answer 1

 300÷125÷8

=300÷(125×
=300÷1000
=0.3
396-96-172-28  
=(396-96)-(172+28)
= 300-200
= 100 

125*24 

= 125*8*3 

= 1000*3

= 3000

=360÷6÷4

=60÷4

=15

240÷48

=240÷24÷2

=10÷2

=5
800÷32
=800÷8÷4
=100÷4
=25
27+456+73 
=(27+73)+456 
＝100+456
＝556
24÷4+56÷4
＝(24+56)÷4
＝80÷4
＝20
2.5×0.7×0.8
＝(2.5×0.8)×0.7
＝60×0.7
＝42
