脱式计算:0.125x7.41x8

0.125x7.41x8 =(0.125×8)×7.41 =1×7.41 =7.41

=0.125×8×4.7 =1×4.7 =4.7

125x64 =125x8x8 =1000x8 =8000

简便计算:(125十40)x8,脱式: (125十40)x8 =125x8+40x8 =1000+320 =1320

53x8X125 =53*(8*125) =53*1000 =53000 直接凑整

=1000÷125×8 =8×8 =64

=400x8-25x8 =3200-200 =3000

1000÷25x8 =40x8 =320 、, 你好,本题已解答,如果满意 请点右上角“采纳答案
