原式=[0.75×42.7-57.3×0.25+57.3×1]÷3×7972=[0.75×42.7-（1-0.25）×57.3]÷3×7972=[0.75×（42.7+57.3）]÷3×7972=0.

0.57X80.6+1.94X5.7

0.57×80.6+1.94×5.7=45.942+11.058=570.25×12.5×3.2=3.125×3.2=10

0.57立方分米=0.57÷1000=0.00057立方米

0.57米等于5分米7厘米1分米=10厘米0.57米=57厘米57/10=5……7所以0.57米=5分米7厘米

57*98%+0.57*2＝57%*98+57%*2＝57%*（98+2）＝57

0.75:

乘以100再答：就是75:100然后化简。再答：请采纳。再答：先拿5约分15:20，然后再拿5约，3:4再答：请采纳

（0.75*42.7+57.3-0.573*25）/3*7972=(0.75*42.7+57.3*1-57.3*0.25)/3*7972=[0.75*42.7+57.3(1-0.25)]/3*7972

42.7-(2.7+2.54)=42.7-2.7-2.54=40-2.54=37.46

这不就等于57呗
