《2025年亮点给力计算天天练五年级数学下册北师大版》

## 一、直接写出得数。（每题1分，共32分）
$\frac{5}{2} \times \frac{4}{5} =$ $\frac{3}{8} \times \frac{2}{9} =$ $\frac{7}{55} \times \frac{33}{14} =$ $\frac{17}{18} - (\frac{1}{4} - \frac{1}{18}) =$
$\frac{8}{7} \times \frac{1}{4} =$ $\frac{7}{9} \times \frac{3}{14} =$ $\frac{12}{13} \times \frac{5}{12} =$ $\frac{5}{6} + \frac{7}{20} + \frac{1}{6} =$
$\frac{1}{2} - \frac{2}{7} =$ $\frac{2}{13} \times \frac{2}{3} =$ $100 \times \frac{4}{25} =$ $3.5 + (\frac{7}{10} - \frac{3}{5}) =$
$\frac{2}{5} + 1.4 =$ $0.9 + \frac{5}{4} =$ $\frac{5}{12} \times \frac{6}{25} =$ $\frac{25}{16} - \frac{7}{6} + \frac{7}{16} =$
$\frac{5}{11} \times \frac{7}{10} =$ $14 \times \frac{7}{18} =$ $\frac{33}{5} \times \frac{5}{22} =$ $\frac{5}{6} + 0.7 \times 0 =$
$\frac{2}{5} \times 6 =$ $\frac{1}{4} \times \frac{1}{4} =$ $\frac{11}{21} \times \frac{7}{44} =$ $4 \div 0.7 \times 0.7 =$
$\frac{3}{5} \times \frac{5}{8} =$ $27 \times 0.02 =$ $\frac{14}{85} \times \frac{17}{7} =$ $\frac{3}{5} + \frac{3}{8} + \frac{5}{8} =$
$\frac{3}{10} \times \frac{35}{27} =$ $\frac{7}{25} \times 20 =$ $\frac{35}{72} \times 36 =$ $\frac{11}{12} - \frac{3}{4} + \frac{1}{6} =$

答案： 2 $\frac{1}{12}$ $\frac{3}{10}$ $\frac{3}{4}$
$\frac{2}{7}$ $\frac{1}{6}$ $\frac{5}{13}$ $1\frac{7}{20}$
$\frac{3}{14}$ $\frac{4}{39}$ 16 3.6
1.8 2.15 $\frac{1}{10}$ $\frac{5}{6}$
$\frac{7}{22}$ $\frac{49}{9}$ $\frac{3}{2}$ $\frac{5}{6}$
$\frac{12}{5}$ $\frac{1}{16}$ $\frac{1}{12}$ 4
$\frac{3}{8}$ 0.54 $\frac{2}{5}$ $1\frac{3}{5}$
$\frac{7}{18}$ $\frac{28}{5}$ $\frac{35}{2}$ $\frac{1}{3}$

## 二、计算下面各题，能简算的要简算。（每题3分，共18分）
$\frac{7}{11} + \frac{2}{33} - \frac{2}{11}$ $\frac{6}{5} + \frac{1}{3} - \frac{5}{6}$ $\frac{26}{25} - (\frac{8}{9} - \frac{4}{25} - \frac{1}{9})$
$\frac{4}{7} - \frac{5}{9} + \frac{4}{9}$ $\frac{7}{10} - (\frac{3}{7} - \frac{3}{10})$ $\frac{9}{13} + \frac{1}{6} + \frac{5}{6} + \frac{4}{13}$

答案： $\frac{17}{33}$ $\frac{7}{10}$ $\frac{1}{5}$
$\frac{29}{63}$ $\frac{4}{7}$ 2
