　　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
　　2.5×3.2×12.5 =(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 3.4÷9＋5.6÷9 =
