37.5%x5/7x3/8 3/8÷7用脱式计算能简便的简便

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

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

脱式计算,能简便的简便: 7又5/8×1/8+3又3/8÷8+0.125 =7又5/8×1/8+3又3/8×1/8+0.125 =(7又5/8+3又3/8+1)×1/8 =12×1/8 =1.5

213.6÷0.8÷0.3 =267÷0.3 =890

(9分之8-3分之1)÷(18分之7x3分之2) =5/9×27/7 =15/7

8.2-9.6x0.5 =8.2-4.8 =3.4

24÷(8/3)怎么脱式计算 解: 根据约分的运用, 原式=24÷(8/3) =24x3/8 =9

8.88×3.7×1.25 =8x1.11x3.7x1.25 =(8x1.25)x1.11x(4-0.3) =10x1.11x4-10x1.11x0.3 =44.4-3.33 =41.07

没有简便计算吧!

7/8-1/3-1/2用脱式计算 =21/24-8/24-12/24 =13/24-12/24 =1/24
