8/15%0.8÷1.5×5/12

8/15-0.8÷1.5×5/12 8/15-0.8÷1.5×5/12 =8/15-8/15*5/12 =8/15*7/12 =2/15*7/3 =14/45

35.8÷12.5÷0.8-0.15 =35.8÷(12.5x0.8)-0.15 =35.8÷10-0.15 =3.58-0.15 =3.43 谢谢,请采纳

35.8÷12.5÷0.8-0.15 =35.8÷(12.5×0.8)-0.15 =35.8÷10-0.15 =3.58-0.15 =3.43

解: 15.6÷0.8÷1.56 =15.6÷ (0.8 * 1.56) =15.6/ (0.8 * 1.56) =10/0.8 =12.5
