7.23+14.75-6.87+2.77-8.75
=（7.23+2.77）+（14.75-8.75）-6.87
=10+6-6.87
=16-6.87
=9.13

7.23+14.76-6.87+2.77-8又4分3简便计算

7.23+14.76-6.87+2.77-8又4分3
=7.23+14.76-6.87+2.77-8.75
=(7.23+2.77)+14.76-(6.87+8.75)
=10+14.76-15.62

7.23+17.75-6.87+2.77-9怎么简便

解：
7.23+17.75-6.87+2.77-9
=（7+0.23）+（18-0.25）-（7-0.13）+（3-0.23）-9
=18-9+3-0.25+0.13
=12-0.12
=11.88

7.23除4十2.77x28简便计算

7.23*28十2.77x28简便计算
7.23*28十2.77x28
=28*(7.23+2.77)
=28*10
=280

用简便方法计算14.75×6.88-8.75×6.88+14.75×3.12-8.75×3.12

原式
=14.75x(6.88+3.12)-8.75x(6.88+3.12)
=14.75x10-8.75x10
=(14.75-8.75)x10
=6x10
=60
或者
=（14.75-8.75）x6.88+(14.75-8.75)x3.12
=6x6.88+6x3.12
=6x(6.88+3.12)
=6x10
=60
