《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)
$\frac{3}{4} × \frac{4}{3} =$ $1 - \frac{3}{4} =$ $\frac{4}{5} × \frac{5}{4} =$ $\frac{2}{27} × 18 =$
$\frac{3}{8} - \frac{3}{10} × \frac{5}{6} =$ $\frac{5}{9} × \frac{9}{5} =$ $\frac{15}{24} × 12 =$ $12 × \frac{11}{16} =$
$5 - 2\frac{3}{7} =$ $36 × (\frac{4}{9} + \frac{5}{6}) =$

答案： 1. $1$ $\frac{1}{4}$ $1$ $\frac{4}{3}$ $\frac{1}{8}$ $1$ $\frac{15}{2}$ $\frac{33}{4}$ $2\frac{4}{7}$ $46$

2. 计算下面各题,能简算的要简算。(18分)
$(\frac{3}{8} + \frac{3}{5}) ÷ \frac{1}{10} × \frac{4}{13}$ $\frac{4}{9} + \frac{7}{15} ÷ \frac{21}{25} - 0.8$
$\frac{6}{5} × \frac{3}{7} - \frac{1}{5} × \frac{3}{7} + \frac{2}{3}$ $\frac{18}{5} ÷ [\frac{12}{5} × (\frac{1}{2} + \frac{2}{3})]$
$(\frac{7}{19} + \frac{21}{17}) × \frac{1}{7} + \frac{14}{17}$ $\frac{1}{10} ÷ [\frac{3}{5} × (\frac{4}{5} - \frac{7}{10})]$

答案： 2. 3 $\frac{2}{9}$ 原式=$(\frac{6}{5}-\frac{1}{5})×\frac{3}{7}+\frac{2}{3}=\frac{3}{7}+\frac{2}{3}=\frac{23}{21}$ $\frac{9}{7}$ 原式=$\frac{7}{19}×\frac{1}{7}+\frac{21}{17}×\frac{1}{7}+\frac{14}{17}=\frac{1}{19}+(\frac{3}{17}+\frac{14}{17})=\frac{1}{19}+1=1\frac{1}{19}$ $\frac{5}{3}$
