(1)3.25×0.45+6.75×0.45=(3.25+6.75)×0.45=10×0.45=4.5;(2)9.07-22.78÷3.4=9.07-6.7=2.37;(3)7.5×102=7.5×(100+2)=7.5×100+7.5×2=750+15=765;(4)5.64÷0.125÷8=5.64÷(0.125×8)=5.64÷1=5.64;(5)16×0.7×2.5=4×4×0.7×2.5=(4×0....

①9.07-22.78÷3.4,=9.07-6.7,=2.37.②12.6÷0.28÷0.9,=45÷0.9,=50.③26.4×0.65+0.35,=17.16+0.35,=17.51.④2.35×14-8.93,=32.9-8.93,=23.97.

0.98×101 =0.98*(100+1) =0.98*100+0.98 =98+0.98 =98.98 9.07-22.78÷3.4 =9.07-6.7 =2.37 0.125×3.2×0.25 =0.125*8*0.4*0.25 =(0.125*8)*(0.4*0.25) =1*0.1 =0.1
