7.25×5.6+1.35×5.6+86×0.44简算

Answer 1

解：采用提取公因式的简便方法 ，
原式=7.25×5.6+1.35×5.6+86×0.44
=（7.25+1.35）x5.6+86x0.44
=8.6x5.6+8.6x4.4
=8.6x（5.6+4.4）
=8.6x10
=86

Answer 2

前两个可为8.6乘以5.6后面可为8.6乘以4.4然后就是8.6乘以十得86了

Answer 3

7.25×5.6+1.35×5.6+86×0.44
＝（7.25+1.35）×5.6+86×0.44
＝8.6*5.6+86*0.44
＝86*0.56+86*0.44
＝86*（0.56+0.44）
＝86*1
＝86
