30.8÷[14-(9.85+1.07)][60-(9.5+28.9)]÷0.182.881÷0.43-0.24×3.520×[(2.44-1.8)÷0.4+0.15]28-(3.4+1.25×2.4
这些是小数的,现在找不到分数的,你只能锻炼锻炼自己,练一下小数化分数了,30.8÷[14-(9.85+1.07)][60-(9.5+28.9)]÷0.182.881÷0.43-0.24×3.520×[
1.3/7×49/9-4/32.8/9×15/36+1/273.12×5/6–2/9×34.8×5/4+1/45.6÷3/8–3/8÷66.4/7×5/9+3/7×5/97.5/2-(3/2+4/5)
没有题怎么做?
