0.36×7.5+0.036×25的简便算法0.36×7.5+0.036×25的简便算法0.36×7.5+0.036×25的简便算法0.36×7.5+0.036×25=0.36×7.5+0.36×2.

0.36×7.5+0.036×25 的简便算法
0.36×7.5+0.036×25 的简便算法

0.36×7.5+0.036×25 的简便算法
0.36×7.5+0.036×25
=0.36×7.5+0.36×2.5
=0.36×(7.5+2.5)
=0.36×10
=3.6

0.36×7.5+0.036×25
=0.36×7.5+0.36×2.5
=(7.5+2.5)×0.36
=10×0.36
=3.6

原题=36*(0.01*7.5+0.001*25)=36*0.1=3.6

0.36x7.5+0.036x25=0.036x75+0.036x25=0.036x(75+25)=0.036x100=3.6

0.36×7.5+0.036×25
=0.36×7.5+0.36×2.5
=0.36×(7.5+2.5)
=0.36×10
=3.6 遇到这种题目,需要观察特点,提取公因式的原理!
