《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）
$\frac{1}{8}\div\frac{3}{8}=$ $\frac{7}{9}\times7=$ $\frac{100}{99}\div50=$ $1 - \frac{3}{8} + \frac{3}{4}=$
$\frac{5}{6} + \frac{3}{10}=$ $24\div\frac{36}{13}=$ $\frac{8}{63}\div\frac{4}{21}=$ $\frac{9}{16} - \frac{1}{2} + \frac{1}{8}=$
$\frac{11}{20}\div\frac{11}{10}=$ $\frac{15}{7}\times\frac{4}{5}=$ $\frac{6}{7}\div\frac{15}{28}=$ $\frac{4}{9} + \frac{1}{3} - \frac{1}{2}=$
$\frac{9}{16}\div\frac{3}{16}=$ $\frac{13}{15}\div52=$ $1.5 + \frac{7}{10}=$ $\frac{1}{2} + \frac{5}{8} + \frac{3}{4}=$
$7\times\frac{3}{14}=$ $3.6 + \frac{5}{4}=$ $\frac{38}{39}\times\frac{78}{57}=$ $\frac{2}{3} + \frac{4}{3} - 1=$
$\frac{9}{8} - \frac{3}{4}=$ $24\div\frac{100}{3}=$ $\frac{15}{34}\div\frac{45}{17}=$ $\frac{3}{5} + \frac{3}{10} + \frac{2}{15}=$
$\frac{1}{6} + \frac{2}{5}=$ $\frac{17}{30}\div\frac{2}{3}=$ $\frac{10}{7}\div\frac{20}{3}=$ $\frac{9}{4} + \frac{2}{3} - 2=$
$\frac{3}{7}\times\frac{1}{3}=$ $\frac{9}{10}\div\frac{3}{20}=$ $\frac{9}{19}\div\frac{12}{19}=$ $\frac{1}{2} + \frac{1}{5} + \frac{3}{8}=$

答案： $\frac{1}{3}$ $\frac{49}{9}$ $\frac{2}{99}$ $\frac{11}{8}$
$\frac{17}{15}$ $\frac{26}{3}$ $\frac{2}{3}$ $\frac{3}{16}$
$\frac{1}{2}$ $\frac{12}{7}$ $\frac{8}{5}$ $\frac{5}{18}$
3 $\frac{1}{60}$ 2.2 $\frac{15}{8}$
$\frac{3}{2}$ 4.85 $\frac{4}{3}$ 1 $\frac{3}{8}$ $\frac{18}{25}$ $\frac{1}{6}$ $\frac{31}{30}$
$\frac{17}{30}$ $\frac{17}{20}$ $\frac{3}{14}$ $\frac{11}{12}$
$\frac{1}{7}$ 6 $\frac{3}{4}$ $\frac{43}{40}$

#### 二、计算下面各题，能简算的要简算。（每题4分，共24分）
$\frac{4}{15} + \frac{5}{12} - \frac{1}{6}$ $\frac{5}{7} - (\frac{13}{14} - \frac{1}{2})$ $\frac{7}{6} - \frac{4}{11} + \frac{5}{6} + \frac{7}{11}$
$2.7\times6.2 + 0.38\times27$ $\frac{9}{10} - (\frac{3}{10} + \frac{2}{15})$ $\frac{1}{6} + \frac{1}{12} + \frac{1}{20} + \frac{1}{30} + \frac{1}{42}$

答案： $\frac{31}{60}$ $\frac{2}{7}$ $2\frac{3}{11}$
27 $\frac{7}{15}$ $\frac{5}{14}$
