答案： 解析：这些题目主要考查分数的加减乘除以及括号内填空的运算。
答案：
1
$1 - \frac{1}{2} - \frac{1}{3} = \frac{1}{6}$
$\frac{1}{2}$
$\frac{5}{6}× \frac{3}{10}×7 = \frac{7}{4}$
3
$\frac{1}{7}$
1
$1 -(\quad) = \frac{5}{8}，(\quad) =\frac{3}{8}$
$\frac{1}{2}$
$(\quad)÷\frac{7}{10} = \frac{1}{2}，(\quad) = \frac{7}{20}$
$\frac{7}{2}$
$(\quad) - \frac{1}{4} = \frac{1}{12}，(\quad) =\frac{1}{3}$
$\frac{1}{9}$
$(\quad)÷\frac{5}{7} = 1，(\quad)=\frac{5}{7}$
$\frac{3}{35}$
$(\quad)÷\frac{2}{3} = 9，(\quad)=6$
$\frac{1}{3}$
$\frac{2}{3}× (\quad) = \frac{1}{2}，(\quad)=\frac{3}{4}$
0
$(\quad)÷\frac{5}{6} = \frac{3}{2}，(\quad)=\frac{5}{4}$
$\frac{20}{9}$
$\frac{7}{12}× (\quad) = \frac{3}{8}，(\quad)=\frac{9}{14}$
