4*25*3+75=375 前面算出来是整数100,后面都比较简单的。

原式 =0.6×(3.625+4.375)×1.25 =0.6×8×1.25 =0.6×10 =6

8分之7乘以0.375加8分之3除以九分之8 =(7/8)x0.375+(3/8)/ (8/9) =(7/8)x(3/8)+(3/8)x (9/8) =(21+27)/64 =48/64 =3/4

0.375乘5分之3加5分之2乘8分之3加2除以8分之3能用简便方法吗 =(3/8)×(3/5)+(3/8)×(2/5)+2÷(3/8) =(3/8)+2×(8/3) =3/8+16/3 =9/24+128/24 =137/24.

原式 =3.375x0.97+0.97x6.625 =(3.375+6.625)x0.97 =10x0.97 =9.7 供参考。

3/8 x 14 +3/8 x 19 - 0.375 =3/8 x (14+19) - 0.375 =3/8 x 33 - 0.375 =99/8 - 0.375 = 12.375 - 0.375 =12

82×3/8加0.375乘以19-3/8简便算法 82×3/8加0.375乘以19-3/8 =3/8*(82+19-1) =3/8*100 =37.5
