1.25×17.6+36÷0.8+2.64×12.5记住简便算法
1.25×17.6+36÷0.8+2.64×12.5
=1.25×17.6+36*1.25+26.4×1.25
=1.25*(17.6+36+26.4)\
=1.25*80
=100

100
自己拿计算器按不比上这问更快………………

1.25×17.6+36÷0.8+2.64×12.5
=1.25×17.6+36×12.5+2.64×12.5
=1.25×(17.6+36+2.64)
=1.25×56.24
=1.25×8×7.03
=70.3

1.25×17.6+36÷0.8+2.64×12.5
=1.25×(17.6+2.64)+36÷0.8
=1.25×20+36×4/5
=25+45
=70

1.25×17.6+36÷0.8+2.64×12.5
=12.5*1.76+2.64*12.5+36/0.8
=12.5*4.4+45=1.25*44+45
=100.
