答案10÷3.14-6.86÷3.14 =(10-6.86)÷3.14 =3.14÷3.14
=1
37.68÷0.25÷4
=37.68÷(0.25×4) =37.68÷1
=37.68
3.75-(2.75-1.3) =3.75-2.75+1.3 =1+1.3
=2.3
37.56-(18+7.56) =37.56-7.56-18 =30-18
=12
0.77÷14
=0.77÷7÷2
=0.11÷2
=0.055
4.5×9.8 =4.5×(10-0.2)
=4.5×10-4.5×0.2
=45-0.9
=44.1
0.7÷0.125
=(0.7×8)÷(0.125×8)
=0.56÷1
=0.56
0.7÷0.25
=(0.7×4)÷(0.25×4)
=2.8÷1
=2.8

3.2×12.5
=(2.5×0.4)×(8×12.5)
=1×100
=100
12.5×9.6×0.25
=(12.5×0.8)×3×(4×0.25) =10×3×1
=30
3.75-(2.8-1.25)
=3.75+1.25-2.8
=5-2.8
=2.2
37.65÷0.4÷0.25
3.125÷8÷0.125
37.65-4.75-3.25
25×6.4×12.5
=25×4×0.2×8×12.5 3.6×0.25
=(4-0.4)×0.25
