如题所述
计算过程如下:
3/4×37+640×75－3/4
=3/4×37－3/4+640×75
=3/4(37－1)+640×75
=3/4×36+640×75
=3×9+640×75
=27+640×75
=27+48000
=48027
望采纳。

3/4*37+640*75-3/4
=0.75*37+640*75-0.75
=75*0.37+640-0.75
=（640+0.37）*75-0.75
=640.37*75-0.75
=48027.75-0.75
=48027
=0.75*37+640*75-0.75
=75*0.37+640-0.75
=（640+0.37）*75-0.75
=640.37*75-0.75
=48027.75-0.75
=48027
