4×0.5×0.25 0.4×16×0.25 0.35×99-0.35×9 23.6-4.5÷0.3 11.25÷7.5×2.3 如何简算?

4×0.5×0.25
=(4×0.25)×0.5
=1×0.5
=0.5
0.4×16×0.25
=(0.4×0.25)×16
=0.1×16
=1.6
0.35×99-0.35×9
=0.35×(99-9)
=0.35×90
=31.5
23.6-4.5÷0.3
=23.6-15
=8.6
11.25÷7.5×2.3
=1.5×2.3
=3.45
再问： 9.6÷1.2+2.4×5 1.008÷0.48+3.76 （480+160）÷（19+21） 98.5-125÷25×12 160+240×0.3-90 20÷0.5-3.45 这些题如何简算呀？拜托啦！！！！！！！！
再答： 9.6÷1.2+2.4×5 =8+12 =20 （直接计算） 1.008÷0.48+3.76 =1008÷480+3.76 =2.1+3.76 =5.86 （480+160）÷（19+21） =640÷40 =16 98.5-125÷25×12 =98.5-5×12 =98.5-60 =38.5 160+240×0.3-90 =160+72-90 =232-90 =152 20÷0.5-3.45 =40-3.45 =36.55 直接计算就行了
