2.5x2.4简便计算

2.5*2.4=2.5*4*0.6=10*0.6=6

=2.5*4*0.6=10*0.6=6

2.5*0.4*6=1*6=6

你好,很高兴地解答你的问题.2.5*2.7*2.4=2.5*2.7*(8*0.3)=0.3*(8*2.5)*2.7=0.3*20* 2.7=20*(0.3*2.7)=20*0.81=20*(0.8+0.01)=20*0.8+20*0.01=16+0.2=16.2

2.5*2.4用简便计算=2.5x4x0.6=10x0.6=6

7.5x0.8-2.5x2.4=2.5*(2.4-2.4)=2.5*0=0

2.5x(0.8+2.4)x1.25 =2.5*3.2*1.25 =5/2*(4-4/5)*5/4 =5/2*[(4-4/5)*5/4] =5/2*[5-1] =5/2*4 =10

12.6x2.4-2.5x2.4=(12.6-2.5)x2.4=10.1x2.4=10x2.4+0.1x2.4=24+0.24=24.24 希望能帮到你

10-2.5*2.4=10-2.5*4*0.6=10-10*0.6=10-6=4

=560÷7÷2-2.5*4*0.6=80÷2-10*0.6=40-6=34
