《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）
$\frac{3}{7} \times \frac{1}{6} =$ $\frac{4}{5} + \frac{1}{15} =$ $\frac{5}{6} \times \frac{3}{20} =$ $\frac{24}{25} - \frac{3}{5} - \frac{2}{25} =$
$\frac{5}{6} \times \frac{1}{8} =$ $\frac{4}{9} \times \frac{5}{8} =$ $\frac{3}{5} - \frac{1}{7} =$ $\frac{1}{4} + \frac{2}{3} + \frac{3}{5} =$
$\frac{8}{15} \times \frac{5}{16} =$ $\frac{5}{12} \times \frac{3}{2} =$ $\frac{5}{9} + \frac{3}{5} =$ $\frac{29}{35} - \frac{2}{5} - \frac{2}{7} =$
$\frac{7}{10} \times \frac{8}{21} =$ $\frac{1}{2} - \frac{3}{8} =$ $\frac{7}{12} \times \frac{4}{35} =$ $7 + \frac{5}{9} + \frac{4}{9} =$
$\frac{9}{14} \times 42 =$ $\frac{8}{15} - 0.4 =$ $\frac{2}{63} \times 9 =$ $\frac{18}{11} - \frac{1}{3} + \frac{4}{11} =$
$\frac{8}{5} \times \frac{35}{48} =$ $\frac{2}{7} + \frac{1}{14} =$ $\frac{9}{17} \times \frac{34}{3} =$ $\frac{9}{10} - \frac{2}{5} + \frac{1}{2} =$
$\frac{7}{8} - \frac{2}{5} =$ $\frac{7}{5} \times 20 =$ $\frac{3}{5} \times 4 =$ $\frac{17}{8} + \frac{5}{12} - \frac{9}{8} =$
$2 - \frac{5}{8} =$ $\frac{8}{11} + \frac{6}{33} =$ $\frac{1}{4} + \frac{2}{9} =$ $\frac{23}{15} - \frac{7}{20} - \frac{13}{20} =$

答案： $\frac{1}{14}$ $\frac{13}{15}$ $\frac{1}{8}$ $\frac{7}{25}$
$\frac{5}{48}$ $\frac{5}{18}$ $\frac{16}{35}$ $\frac{91}{60}$
$\frac{1}{6}$ $\frac{5}{8}$ $\frac{52}{45}$ $\frac{1}{7}$
$\frac{4}{15}$ $\frac{1}{8}$ $\frac{1}{15}$ 8
27 $\frac{2}{15}$ $\frac{2}{7}$ $1\frac{2}{3}$
$\frac{7}{6}$ $\frac{5}{14}$ 6 1
$\frac{19}{40}$ 28 $\frac{12}{5}$ $\frac{17}{12}$
$1\frac{3}{8}$ $\frac{10}{11}$ $\frac{17}{36}$ $\frac{8}{15}$

## 二、计算下面各题，能简算的要简算。（每题3分，共18分）
$\frac{5}{6} + \frac{3}{4} - \frac{1}{3}$ $\frac{29}{24} - (\frac{5}{24} - \frac{4}{9})$ $\frac{9}{4} - \frac{3}{7} + \frac{5}{4} - \frac{4}{7}$
$\frac{11}{15} - \frac{3}{4} + \frac{4}{15}$ $\frac{21}{16} - \frac{5}{9} + \frac{11}{16}$ $2 - (\frac{7}{8} + \frac{1}{12}) - \frac{1}{8}$

答案： $\frac{5}{4}$ $1\frac{4}{9}$ $\frac{5}{2}$
$\frac{1}{4}$ $1\frac{4}{9}$ $\frac{11}{12}$
