《2025年直击考点冲刺100分六年级数学上册苏教版》

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

答案： 1. $\frac {3}{8}$ $\frac {3}{5}$ $\frac {5}{12}$ $\frac {1}{6}$ $\frac {1}{5}$ 4 $\frac {2}{5}$ $2\frac {3}{4}$ 1 $\frac {4}{5}$

2. 计算下面各题,能简算的要简算。(18分)
$[\frac{1}{2} - (\frac{3}{4} - \frac{3}{5})] ÷ \frac{7}{10}$ $\frac{13}{5} × 13 + \frac{13}{5} ÷ \frac{1}{7}$
$\frac{8}{15} ÷ [\frac{1}{4} × (\frac{8}{9} - \frac{16}{45})]$ $\frac{7}{8} × 2.5 × \frac{6}{7} × 0.4$
$(\frac{4}{5} - \frac{1}{4}) ÷ \frac{11}{12} ÷ \frac{7}{10}$ $5 × (\frac{4}{5} - \frac{2}{7}) × 7$

答案： 2. $\frac {1}{2}$ 原式=$\frac {13}{5}$×$(13+7)=\frac {13}{5}×20=52$ 4 原式=$(\frac {7}{8}×\frac {6}{7})×(2.5×0.4)=\frac {3}{4}×1=\frac {3}{4}$ $\frac {6}{7}$ 18
