37.5%x5/7x3/8 3/8÷7用脱式计算能简便的简便

37.5%×5/7+1/7×3/8+3/8÷7 =3/8×5/7+1/7×3/8+3/8×1/7 =3/8×(5/7+1/7+1/7) =3/8×1 =3/8

3/8+7/8+5/8 =15/8 -------------------------------

37.5%*5/7+1/7x3/8+3/8÷7 =3/8*5/7+3/8*1/7+1/8*1/7 =3/8*(5/7+1/7+1/7) =3/8*1 =3/8

[(7/9+1/3)÷(1/3+1/5)]×3/10 =[10/9÷8/15]×3/10 =10/9×3/10÷8/15 =1/3÷8/15 =5/8

0.375×3/5+2/5×37.5%+2÷8简便脱式计算怎么算 0.375×3/5+2/5×37.5%+2÷8 =3/8*(3/5+2/5)+1/4 =3/8*1+1/4 =3/8+1/4 =5/8

(1/8-3/14+1/7)*12 =【1/8-(3/14-1/7)】*12 =【1/8-1/14】*12 =1/8*12-1/14*12 =3/2-6/7 =9/14

7.8÷0.26÷0.3 =7.8÷(0.26×0.3) =7.8÷0.78 =10,

5/8+5/11+0.375 =5/8+5/11+3/8 =5/8+3/8+5/11 =1+5/11 =1又11分之5
