8.直接写出得数.
0.12= | 2-40%= | $\frac{2}{15}×\frac{3}{4}$= | 0÷2.54= |
8-0.12-0.88= | 3.14×20= | 26×50= | 25×0.2= |
10-0.86= | 24×$\frac{3}{4}$= | $\frac{3}{7}$÷3= | 125%×8= |
4.8÷0.8= | 8÷$\frac{4}{5}$= | 1-1÷9= | $\frac{2}{3}$-$\frac{2}{3}$×0= |
12×($\frac{1}{4}$+$\frac{1}{6}$)= | $\frac{8}{9}$×$\frac{9}{24}$= | $\frac{7}{9}$-$\frac{1}{3}$= | 7.45+8.55= |
1.怎样算简便就怎样算.
4-$\frac{5}{11}$-$\frac{6}{11}$ | $\frac{1}{8}$×58+42÷8 | 72×($\frac{2}{3}$+$\frac{1}{6}$-$\frac{3}{4}$) |
($\frac{1}{2}$-$\frac{3}{8}$)÷$\frac{3}{4}$ | ($\frac{5}{12}$-$\frac{3}{5}$)-($\frac{2}{5}$-$\frac{7}{12}$) | $\frac{4}{9}$÷[$\frac{5}{6}$-($\frac{1}{6}$+$\frac{1}{3}$)] |
20.对称轴最少的图形是( )
