3．脱式计算，能简算的要简算．
| （$\frac{5}{6}$-$\frac{5}{9}$）×$\frac{18}{5}$ | $\frac{6}{13}$×$\frac{7}{5}$-$\frac{6}{13}$×$\frac{2}{5}$ | $\frac{4}{5}$÷[（$\frac{3}{5}$+$\frac{1}{2}$）×2] |
| 34×$\frac{34}{35}$ | 1-$\frac{5}{8}$÷$\frac{25}{28}$-$\frac{3}{10}$ | $\frac{3}{5}$×99+$\frac{3}{5}$ |
2．直接写出得数
0 158602 158610 158616 158620 158626 158628 158632 158638 158640 158646 158652 158656 158658 158662 158668 158670 158676 158680 158682 158686 158688 158692 158694 158696 158697 158698 158700 158701 158702 158704 158706 158710 158712 158716 158718 158722 158728 158730 158736 158740 158742 158746 158752 158758 158760 158766 158770 158772 158778 158782 158788 158796 199269
| 3-1.95= | $\frac{7}{8}$-$\frac{3}{4}$= | $\frac{2}{3}$÷$\frac{3}{2}$= | $\frac{1}{3}$×27= | 0×$\frac{7}{8}$+$\frac{1}{8}$= |
| $\frac{7}{8}$÷$\frac{7}{10}$= | 5÷$\frac{2}{3}$= | $\frac{4}{3}$×75%= | 0.36×$\frac{5}{12}$= | $\frac{3}{8}$+$\frac{5}{8}$×16= |
