1. 直接写出得数。
$\frac{4}{5}×10 =$ $\frac{16×5}{8} =$ $\frac{5}{6}×\frac{18}{35} =$ $\frac{3}{11}×\frac{55}{3} =$
$\frac{3}{4}+\frac{2}{3} =$ $\frac{3}{8}-\frac{1}{4} =$ $\frac{5}{9}×\frac{9}{10} =$ $\frac{7}{18}×10 =$
$\frac{6}{7}×\frac{1}{3} =$ $\frac{1}{2}×\frac{4}{7} =$ $\frac{4}{9}×\frac{5}{8} =$ $10+\frac{1}{5} =$
$\frac{9}{14}×\frac{7}{15} =$ $\frac{10}{51}×\frac{34}{25} =$ $\frac{5}{6}-\frac{3}{7} =$ $\frac{1}{24}×\frac{3}{5} =$
$\frac{7}{10}×\frac{5}{14} =$ $\frac{5}{7}×\frac{2}{15} =$ $10×\frac{9}{20} =$ $75×\frac{1}{3} =$
$\frac{4}{9}+\frac{14}{9} =$ $\frac{5}{39}×13 =$ $\frac{3}{14}×\frac{7}{8} =$ $\frac{3}{23}×\frac{23}{50} =$
$\frac{11}{35}×\frac{15}{22} =$ $\frac{5}{19}×\frac{9}{10} =$ $\frac{1}{4}×\frac{8}{15} =$ $\frac{1}{12}×60 =$

答案： 8@@10@@$\frac{3}{7}$@@5@@$\frac{17}{12}$@@$\frac{1}{8}$@@$\frac{1}{2}$@@$\frac{35}{9}$@@$\frac{2}{7}$@@$\frac{2}{7}$@@$\frac{5}{18}$@@$10\frac{1}{5}$@@$\frac{3}{10}$@@$\frac{4}{15}$@@$\frac{17}{42}$@@$\frac{1}{40}$@@$\frac{1}{4}$@@$\frac{2}{21}$@@$\frac{9}{2}$@@25@@2@@$\frac{5}{3}$@@$\frac{3}{16}$@@$\frac{3}{50}$@@$\frac{3}{14}$@@$\frac{9}{38}$@@$\frac{2}{15}$@@5

2. 口算。
$( )×\frac{4}{15}=1$ $\frac{5}{6}×( ) = 1$ $7×( ) = 1$
$\frac{5}{12}×( ) = 1$ $\frac{7}{16}×( ) = 1$ $\frac{3}{5}×( ) = 1$
$1\frac{1}{2}×( ) = 1$ $( )×2.5 = 1$ $4.5×( ) = 1$
$63×( ) = 1$ $\frac{7}{9}×( ) = 1$ $5\frac{4}{11}×( ) = 1$
$( )×\frac{42}{29} = 1$ $2\frac{1}{3}×( ) = 1$ $( )×1\frac{1}{6} = 1$

答案： $\frac{15}{4}$@@$\frac{6}{5}$@@$\frac{1}{7}$@@$\frac{12}{5}$@@$\frac{16}{7}$@@$\frac{5}{3}$@@$\frac{2}{3}$@@$\frac{2}{5}$@@$\frac{2}{9}$@@$\frac{1}{63}$@@$\frac{9}{7}$@@$\frac{11}{59}$@@$\frac{29}{42}$@@$\frac{3}{7}$@@$\frac{6}{7}$

3. 在$\bigcirc$里填上“$＞$”“$＜$”或“$=$”。
$\frac{2}{3}×\frac{3}{5}\bigcirc\frac{2}{3}$ $\frac{15}{7}×\frac{3}{4}\bigcirc\frac{3}{4}$ $\frac{7}{22}×\frac{3}{20}\bigcirc\frac{3}{20}×\frac{7}{22}$
$\frac{7}{10}\bigcirc\frac{4}{7}×\frac{7}{10}$ $\frac{9}{11}×2\bigcirc\frac{9}{11}×\frac{1}{2}$ $\frac{1}{2}+\frac{5}{4}×\frac{1}{2}\bigcirc(\frac{1}{2}+\frac{5}{4})×\frac{1}{2}$

答案： ＜@@＞@@=@@＞@@＞@@＞
