0.5*236*59/119的简便计算过程
问题描述：
0.5*236*59/119的简便计算过程
答
(0.5*10^5)^3*(4*10^3)^2
=(0.5*10^5)*(0.5*10^5)^2*(4*10^3)^2
=(0.5*10^5)*[(0.5*10^5)*(4*10^3)]^2
=(0.5*10^5)*(2*10^8)^2
=(0.5*10^5)*4*10^16
=0.5*4*10^5*10^16
=2*10^21
答
=118*59/119
=(119-1)*59/119
=119*59/119-1*59/119
=59-59/119
=58+60/119
=58又60/119
答
0.5*236*59/119
=118*59/119
=（119*59-59）/119
=59-59/119
=58又60/119
