答案
$\frac{6}{13} ÷ \frac{3}{26} = 4$
$32 ÷ \frac{8}{3} = 12$
$4.8 ÷ \frac{8}{5} = 3$
$2 - \frac{2}{3} = \frac{4}{3}$
$\frac{11}{12} - \frac{1}{4} = \frac{2}{3}$
$2 × \frac{3}{10} = \frac{3}{5}$
$3 ÷ 9 = \frac{1}{3}$
$\frac{3}{4} - \frac{1}{5} = \frac{11}{20}$
$\frac{5}{7} ÷ \frac{5}{21} = 3$
$0.56 × \frac{8}{7} = 0.64$
$0.75 × 100 = 75$
$1.5 ÷ \frac{15}{16} = 1.6$
$\frac{32}{3} × \frac{9}{8} = 12$
$25.12 ÷ 3.14 ÷ 2 = 4$
$1 ÷ 0.25 = 4$
$\frac{1}{7} + \frac{1}{3} = \frac{10}{21}$
$32 ÷ \frac{8}{3} = 12$
$4.8 ÷ \frac{8}{5} = 3$
$2 - \frac{2}{3} = \frac{4}{3}$
$\frac{11}{12} - \frac{1}{4} = \frac{2}{3}$
$2 × \frac{3}{10} = \frac{3}{5}$
$3 ÷ 9 = \frac{1}{3}$
$\frac{3}{4} - \frac{1}{5} = \frac{11}{20}$
$\frac{5}{7} ÷ \frac{5}{21} = 3$
$0.56 × \frac{8}{7} = 0.64$
$0.75 × 100 = 75$
$1.5 ÷ \frac{15}{16} = 1.6$
$\frac{32}{3} × \frac{9}{8} = 12$
$25.12 ÷ 3.14 ÷ 2 = 4$
$1 ÷ 0.25 = 4$
$\frac{1}{7} + \frac{1}{3} = \frac{10}{21}$
2. 接着算。

$\frac{3}{4} × \frac{2}{3}$ ______ $+ \frac{1}{6}$ ______ $÷ \frac{1}{2}$ ______ $- \frac{5}{6}$ ______
$\frac{3}{5} ÷ \frac{9}{10}$ ______ $- \frac{1}{3}$ ______ $× \frac{6}{7}$ ______ $+ \frac{1}{2}$ ______

$\frac{3}{5} ÷ \frac{9}{10}$ ______ $- \frac{1}{3}$ ______ $× \frac{6}{7}$ ______ $+ \frac{1}{2}$ ______
答案
$\frac{3}{4}×\frac{2}{3}=\frac{1}{2}$
$\frac{1}{2}+\frac{1}{6}=\frac{2}{3}$
$\frac{2}{3}÷\frac{1}{2}=\frac{4}{3}$
$\frac{4}{3}-\frac{5}{6}=\frac{1}{2}$
$\frac{3}{5}÷\frac{9}{10}=\frac{2}{3}$
$\frac{2}{3}-\frac{1}{3}=\frac{1}{3}$
$\frac{1}{3}×\frac{6}{7}=\frac{2}{7}$
$\frac{2}{7}+\frac{1}{2}=\frac{11}{14}$
依次填入的结果为:$\frac{1}{2}$,$\frac{2}{3}$,$\frac{4}{3}$,$\frac{1}{2}$;$\frac{2}{3}$,$\frac{1}{3}$,$\frac{2}{7}$,$\frac{11}{14}$。
$\frac{1}{2}+\frac{1}{6}=\frac{2}{3}$
$\frac{2}{3}÷\frac{1}{2}=\frac{4}{3}$
$\frac{4}{3}-\frac{5}{6}=\frac{1}{2}$
$\frac{3}{5}÷\frac{9}{10}=\frac{2}{3}$
$\frac{2}{3}-\frac{1}{3}=\frac{1}{3}$
$\frac{1}{3}×\frac{6}{7}=\frac{2}{7}$
$\frac{2}{7}+\frac{1}{2}=\frac{11}{14}$
依次填入的结果为:$\frac{1}{2}$,$\frac{2}{3}$,$\frac{4}{3}$,$\frac{1}{2}$;$\frac{2}{3}$,$\frac{1}{3}$,$\frac{2}{7}$,$\frac{11}{14}$。

答案
补充表格(从左到右空缺处结果):
商第一空:$25\% ÷ \frac{8}{3} = \frac{3}{32}$
被除数第一空:$\frac{4}{3} × 0.75 = 1$
除数第一空:$2.4 ÷ \frac{3}{5} = 4$
被除数第二空:$\frac{3}{10} × \frac{5}{6} = \frac{1}{4}$
除数第二空:$\frac{4}{7} ÷ \frac{16}{21} = \frac{3}{4}$
商第二空:$15 ÷ \frac{3}{8} = 40$
被除数第三空:$80\% × \frac{5}{6} = \frac{2}{3}$
---
$42 ÷ 12 = 3······6$
$3 + 1 = 4$(人)
答:他们中至少有4人在同一个月出生。
