《2025年口算天天练每日5分钟六年级数学上册苏教版》

一、口算。
$\frac {8}{25}÷\frac {4}{5}=$
$\frac {3}{2}×\frac {2}{25}=$
$\frac {4}{25}-\frac {1}{50}=$
$\frac {26}{5}÷13=$
$\frac {5}{12}×\frac {9}{10}=$
$\frac {3}{4}÷\frac {1}{4}=$
$\frac {4}{3}-\frac {1}{4}=$
$\frac {39}{40}÷\frac {13}{10}=$
$\frac {5}{9}÷\frac {2}{3}=$
$14×\frac {8}{7}=$
$\frac {20}{27}÷\frac {4}{9}=$
$\frac {7}{4}+\frac {1}{2}=$
$\frac {9}{10}÷\frac {3}{5}=$
$\frac {8}{5}-\frac {7}{6}=$
$42÷\frac {7}{8}=$
$\frac {6}{7}×\frac {5}{9}=$
$\frac {5}{8}÷\frac {5}{12}=$
$15×\frac {4}{5}=$
$\frac {7}{3}÷5=$
$\frac {21}{5}×\frac {35}{6}=$
$\frac {9}{2}÷\frac {12}{5}=$

答案： 1.$\frac{2}{5}$ 2.$\frac{3}{25}$ 3.$\frac{7}{50}$ 4.$\frac{2}{5}$ 5.$\frac{3}{8}$ 6.3 7.$\frac{13}{12}$ 8.$\frac{3}{4}$ 9.$\frac{5}{6}$ 10.16 11.$\frac{5}{3}$ 12.$\frac{9}{4}$ 13.$\frac{3}{2}$ 14.$\frac{13}{30}$ 15.48 16.$\frac{10}{21}$ 17.$\frac{3}{2}$ 18.12 19.$\frac{7}{15}$ 20.$\frac{49}{2}$ 21.$\frac{15}{8}$

二、计算下面各题,怎样简便就怎样计算。
$\frac {20}{13}÷7+\frac {1}{7}×\frac {6}{13}$
$(1-\frac {1}{8}×\frac {16}{9})÷\frac {7}{9}$
$\frac {5}{6}×\frac {6}{5}-\frac {9}{10}÷\frac {9}{5}$

答案： 1.$\frac{2}{7}$ 2.1 3.$\frac{1}{2}$
