《2025年同步跟踪全程检测六年级数学上册苏教版》

1. 直接写出得数。(8分)
$\frac {5}{7}×\frac {3}{5}=$$\frac{3}{7}$ $\frac {5}{6}÷\frac {5}{8}=$$\frac{4}{3}$ $11×\frac {8}{121}=$$\frac{8}{11}$
$\frac {1}{7}×\frac {8}{9}÷\frac {1}{7}=$$\frac{8}{9}$ $0÷\frac {2}{9}×\frac {9}{4}=$0 $1-\frac {5}{12}+\frac {7}{12}=$$\frac{7}{6}$
$12×(\frac {1}{3}+\frac {1}{4})=$7 $5÷\frac {5}{6}-\frac {5}{6}÷5=$$5\frac{5}{6}$(或$\frac{35}{6}$)

答案： $\frac{3}{7}$ $\frac{4}{3}$ $\frac{8}{11}$ $\frac{8}{9}$ 0 $\frac{7}{6}$ 7 $5\frac{5}{6}$(或$\frac{35}{6}$)

2. 下面各题,怎样算简便就怎样算。(18分)
$\frac {7}{20}×99+\frac {7}{20}$ $\frac {16}{11}-(\frac {1}{3}÷\frac {11}{15}+\frac {1}{5})$ $(\frac {5}{7}+\frac {1}{15})×7+\frac {8}{15}$
$\frac {8}{5}-\frac {6}{7}÷2-\frac {4}{7}$ $15×(\frac {2}{5}-\frac {1}{19})×19$ $\frac {9}{8}÷[(\frac {2}{5}+\frac {1}{10})×\frac {3}{4}]$

答案： 35 $\frac{4}{5}$ 6 $\frac{3}{5}$ 99 3

3. 解方程。(9分)
$\frac {1}{3}+\frac {7}{18}x= \frac {23}{27}$ $\frac {4}{5}x×\frac {3}{2}= 6$ $\frac {5}{6}x÷\frac {2}{3}= \frac {5}{18}$

答案： $x=\frac{4}{3}$ $x=5$ $x=\frac{2}{9}$

1. (180)米比150米多$\frac {1}{5}$;比($69\frac{1}{2}$(或69.5))千克多$\frac {1}{2}$千克是70千克。

答案： 180 $69\frac{1}{2}$(或69.5)

$\frac {2}{3}-\frac {1}{15}=$\frac{3}{5}$$ $\frac {3}{8}÷$\frac{3}{5}$=$\frac{5}{8}$$ $$\frac{5}{8}$×\frac {16}{15}=$\frac{2}{3}$$
综合算式:$\frac{3}{8}÷(\frac{2}{3}-\frac{1}{15})×\frac{16}{15}=\frac{2}{3}$

答案： $\frac{2}{3}$ $\frac{3}{8}$÷$(\frac{2}{3}-\frac{1}{15})×\frac{16}{15}=\frac{2}{3}$
