0.75×0.76+0.26×0.75的简便运算
=0.75x（0.76+0.26）
=0.75x（1+0.02）
=0.75+0.75x0.02
=0.75+0.015
=0.765
0.75×0.76+0.26×0.75
=0.75×(0.76+0.26)
=0.75×1.02
=0.75×(1+0.02)
=0.75×1+0.75×0.02
=0.75+0.015
=0.765
=0.75x(0.76+0.26)
=0.75×(1+0.02)
=0.75+0.015
=0.765
题目有错。不能简便计算。
0.75×0.76+0.24×0.75
=0.75×（0.76+0.24）
=0.75×1
=0.75
