7.5*46.7+59.9*2.5的简便计算怎么写
7.5*46.7+59.9*2.5的简便计算怎么写

7.5*46.7+59.9*2.5的简便计算怎么写
7.5*(50-3.3)+(60-0.1)*2.5
=7.5*50-3.3*7.5+60*2.5-0.1*0.25
=2.5*150+60*2.5-9.9*2.5-0.1*2.5
=210*2.5-10*2.5
=200*2.5
=500

7.5*46.7+59.9*2.5=2.5*(3*46.7+59.9)=2.5*(140.1+59.9)=2.5*200=500

2.5*(3*46.7)+2.5*59.9=2.5*140.1+2.5*59.9=2.5*(140.1+59.9)=2.5*160=2.5*4*40=400

7.5*46.7+59.9*2.5
=2.5×3×46.7+59.9×2.5
=2.5×140.1+59.9×2.5
=2.5×(140.1+59.9)
=2.5×200
=500
