《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）
$15\div\frac{5}{8}=$ $20\times\frac{7}{15}=$ $36\times\frac{5}{24}=$ $\frac{8}{9}\div4=$
$\frac{8}{27}\div\frac{4}{9}=$ $\frac{3}{11}\div\frac{9}{22}=$ $\frac{3}{5}\div\frac{9}{10}=$ $\frac{2}{3}\div\frac{3}{4}=$
$\frac{2}{23}\div\frac{3}{46}=$ $\frac{6}{7}\div\frac{3}{14}=$ $\frac{8}{27}\div\frac{4}{5}=$ $48\times\frac{3}{8}=$
$\frac{15}{16}\div\frac{5}{4}=$ $\frac{2}{15}\div\frac{3}{5}=$ $27\div\frac{9}{7}=$ $\frac{9}{5}\div15=$
$\frac{10}{13}\div\frac{5}{13}=$ $\frac{1}{6}\div\frac{4}{9}=$ $\frac{7}{15}\times90=$ $\frac{15}{8}\div3=$
$33\times\frac{9}{22}=$ $\frac{7}{15}\times\frac{10}{21}=$ $12\div\frac{6}{11}=$ $66\times\frac{9}{11}=$
$0\div\frac{79}{100}=$ $\frac{32}{7}\div16=$ $\frac{9}{20}\times\frac{5}{9}=$ $\frac{5}{2}\div\frac{1}{3}=$
$\frac{5}{9}\div\frac{20}{27}=$ $\frac{9}{32}\times32=$ $70\times\frac{32}{35}=$ $\frac{12}{13}\div\frac{4}{39}=$

答案： 24 $\frac{28}{3}$ $\frac{15}{2}$ $\frac{2}{9}$
$\frac{2}{3}$ $\frac{2}{3}$ $\frac{2}{3}$ $\frac{8}{9}$
$\frac{4}{3}$ 4 $\frac{10}{27}$ 18
$\frac{3}{4}$ $\frac{2}{9}$ 21 $\frac{3}{25}$
2 $\frac{3}{8}$ 42 $\frac{5}{8}$
$\frac{27}{2}$ $\frac{2}{9}$ 22 54
0 $\frac{2}{7}$ $\frac{1}{4}$ $\frac{15}{2}$
$\frac{3}{4}$ 9 64 9

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

答案： $\frac{5}{6}$ $\frac{23}{24}$ $1\frac{11}{18}$ $\frac{1}{3}$ $\frac{19}{24}$ $\frac{1}{2}$
