答案=4.5 × (10 -0.2)

10÷3.14-6.86÷3.14 =4.5 × 10— 4.5 × 0.2

-0.9

=(10-6.86) ÷3.14 =45

=3.14 ÷ 3.14 =44.1

37.68 ÷0.25 ÷4 =(0.7

=37.68 ÷(0.25 ×4) =0.56÷1

=37.68 ÷1 =0.56

=37.68

× 4)÷(0.25 × 4)

3.75 -(2.75 -1.3) =(0.7

=3.75 - 2.75 +1.3 =2.8÷1

=1+1.3 =2.8

37.56 -(18 +7.56) =(2.5 × 0.4) ×(8×12.5)

=37.56 -7.56 -18 =1×100

=30-18 =100

=0.77÷7÷2 =10× 3× 1

=0.11 ÷ 2 =30

=0.055 3.75—(2.8 —1.25)

4.5 ×9.8 =3.75+1.25—2.8

=5-2.8

=2.2
