7.26×0.1+0.5×72.6+0.049×726用综合算式简便运算怎么算？

怎么写

Answer 1

解，原式=7.26x0.1+0.5x(7.26x10)+0.049x(100X7.26)
=7.26X0.1+0.5X10X7.26+0.049X100X7.26
=7.26x(0.1+5+4.9)
=7.26x10
=72.6

Answer 2

题目是7.26*0.1+0.5*72.6+0.049*726
7.26*0.1+0.5*72.6+0.049*726
解：原式=7.26*0.1+5*7.26+4.9*7.26
=7.26*（0.1+5+4.9）
=7.26*10
=72.6
