75×96加12×25简便计算

75 x 96 + 12 x 25 =75 x 96 + 4 x 75 =75 x (96 + 4) =75 x 100 =7500 希望我的回答对您有帮助,满意请采纳,谢谢。

75x96+12x25 =75x96+4x3x25 =75x96+4x75 =75x(96+4) =75x100 =7500

25*(3*96+12) =25*3*(96+4) =75*100 =7500

96×25 =(100-4)×25 =100×25-4×25 =2500-100 =2400

96x125x25 =8x4x3x125x25 =(8x125)x(4x25)x3 =1000x100x3 =300000

25×64×96 =25*4*16*(100-4) =1600*100-1600*4 =160000-6400 =153600

96.75×9 =96.75×(10-1) =96.75×10-96.75×1 =967.5-96.75 =870.75 64.5×31 =64.5×(30+1) =64.5×30+64.5×1 =1935+64.5 =1999.5 32.25×11 =32.25×(10+1) =32.25×10+32.25×1 =322.5+32.25 =354.75

96x25x125 =4x8x3x25x125 =(4x25)x(8x125)x3 =100x1000x3 =300000

解如图。

125x25x96 =125x8x12x25 =1000x300 =300000
