1. 直接写出得数。
$39\times\frac{10}{13}=$ $\frac{6}{7}\times\frac{7}{6}=$ $\frac{5}{11}+\frac{5}{11}=$ $\frac{1}{5}-\frac{1}{8}=$
$\frac{1}{6}\times\frac{12}{17}=$ $\frac{7}{8}\times\frac{10}{21}=$ $\frac{5}{36}\times20=$ $\frac{16}{27}\times\frac{3}{2}=$
$\frac{1}{9}+\frac{3}{5}=$ $\frac{2}{3}\times8=$ $\frac{5}{12}\times\frac{3}{4}=$ $\frac{11}{24}\times\frac{16}{33}=$
$\frac{1}{7}-\frac{1}{8}=$ $7+\frac{4}{7}=$ $\frac{1}{8}\times\frac{1}{9}=$ $\frac{8}{9}\times\frac{15}{4}=$
$\frac{11}{12}\times\frac{6}{11}=$ $\frac{9}{4}\times\frac{1}{27}=$ $\frac{5}{8}+\frac{3}{5}=$ $\frac{5}{32}\times\frac{4}{25}=$
$\frac{9}{10}-\frac{7}{10}=$ $\frac{3}{5}\times\frac{3}{8}=$ $24\times\frac{7}{8}=$ $\frac{3}{40}\times\frac{8}{27}=$
$\frac{3}{5}\times\frac{5}{6}=$ $48\times\frac{5}{16}=$ $\frac{3}{8}\times\frac{8}{7}=$ $\frac{5}{12}\times96=$
$\frac{7}{16}\times\frac{4}{7}=$ $\frac{30}{19}\times38=$ $\frac{1}{3}+\frac{5}{6}=$ $51\times\frac{3}{17}=$

2. 在括号里填上合适的数。
$3\ dm^3 = ($ $)mL$ $3.42\ m^3 = ($ $)dm^3$
$705\ cm^3 = ($ $)dm^3$ $12.5\ dm^3 = ($ $)mL$
$12\ dm^3 = ($ $)L = ($ $)mL$ $5\ m^330\ dm^3 = ($ $)m^3$
