《2025年小学数学计算高手每日10分钟六年级数学下册苏教版》

1. 看谁算的又快又准。
$\frac{1}{8}\times\frac{8}{3}=$ $\frac{3}{2}+\frac{5}{6}=$ $\frac{11}{3}\times\frac{2}{5}=$
$\frac{2}{13}-\frac{1}{26}=$ $\frac{2}{3}\times\frac{5}{6}=$ $\frac{19}{36}-\frac{1}{6}=$
$\frac{4}{9}\times\frac{1}{2}=$ $\frac{17}{30}\div\frac{17}{15}=$ $\frac{1}{3}\div1=$
$\frac{1}{2}+\frac{1}{8}=$ $\frac{4}{5}-\frac{2}{5}=$ $\frac{3}{8}\times2=$
$\frac{1}{2}\times\frac{1}{3}=$ $40\times\frac{2}{5}=$ $\frac{5}{7}+\frac{4}{7}=$
$\frac{5}{2}-\frac{1}{3}=$ $12\div\frac{12}{11}=$ $\frac{9}{2}-4=$
$\frac{11}{13}+\frac{22}{39}=$ $\frac{13}{8}-\frac{2}{3}=$ $\frac{4}{5}\times\frac{1}{4}=$
$\frac{5}{8}\times\frac{9}{10}=$ $\frac{5}{6}\div\frac{2}{3}=$ $\frac{1}{8}+\frac{7}{24}=$

答案： $\frac{1}{3}$ $\frac{7}{3}$ $\frac{22}{15}$ $\frac{3}{26}$ $\frac{5}{9}$ $\frac{13}{36}$ $\frac{2}{9}$ $\frac{1}{2}$ $\frac{1}{3}$ $\frac{5}{8}$ $\frac{2}{5}$ $\frac{3}{4}$ $\frac{1}{6}$ 16 $\frac{9}{7}$ $\frac{13}{6}$ 11 $\frac{1}{2}$ $\frac{55}{39}$ $\frac{23}{24}$ $\frac{1}{5}$ $\frac{9}{16}$ $\frac{5}{4}$ $\frac{5}{12}$

2. 脱式计算。
$\frac{9}{20}\times\frac{4}{15}\times\frac{10}{17}$ $\frac{6}{25}+\frac{8}{15}\times\frac{10}{11}$ $\frac{5}{42}\div(\frac{3}{10}-\frac{2}{15})$
$(\frac{17}{40}+\frac{1}{20})\div\frac{27}{50}$ $\frac{20}{21}+(\frac{8}{11}+\frac{22}{21})$ $\frac{13}{18}\times\frac{9}{20}\times\frac{10}{17}$

答案： $\frac{3}{85}$ $\frac{218}{275}$ $\frac{25}{21}$ $\frac{25}{36}$ $\frac{64}{33}$ $\frac{13}{68}$
