3.67乘2.8加3.67乘7.2简便计算 125减100除（2.07减1.27）简便计算

快很急的

Answer 1

3.67乘2.8加3.67乘7.2
=3.67x(2.8+7.2)
=3.67x10
=36.7

125减100除（2.07减1.27）
=125-100÷0.8
=125-125
=0

不懂可追问，有帮助请采纳，谢谢！

23.95减(10.8加3.95)简便计算 （24加9.6除2.4）乘0.5简便算法 麻烦了谢谢

Answer 2

3.67乘2.8加3.67乘7.2
3.67×(2.8+7.2)
=3.67×10
=36.7

125减100÷（2.07减1.27）
=125-100÷0.8
=125-125
=0

追答

23.95减(10.8加3.95)=23.96-3.96-10.8
=20-10.8
=9.2

（24加9.6÷2.4）乘0.5
=（24+4）×0.5
=28×0.5
=14

Answer 3

3.67×（2.8+7.2）=3.67×10=36.7
125-100÷（2.07-1.27）=125-100÷0.8=125-125=0

Answer 4

3.67×2.8+3.67×7.2
=3.67×(2.8+7.2)
=3.67×10
=36.7

125-100÷(2.07-1.27)
=125-100÷0.8
=125-(125×0.8)÷0.8
=125-125
=0

Answer 5

3.67*（2.8+7.2）=3.67*10=36.7
