2026年通城学典计算能手六年级数学下册苏教版江苏专版第101页答案
一、口算。
$1.3 - 0.5 =$
0.8

$1.8×500 =$
900

$10.4÷2.6 =$
4

$1000 - 458 =$
542

$90 + 530 =$
620

$\dfrac{7}{12}×\dfrac{9}{10} =$
$\dfrac{21}{40}$

$20\%+\dfrac{7}{12} =$
$\dfrac{47}{60}$

$0.625×4 =$
2.5

$\dfrac{7}{8}+\dfrac{4}{15} =$
$\dfrac{137}{120}$

$4800÷12 =$
400

$80.7\%-76.9\% =$
3.8%

$41.6 - 6.2 =$
35.4

$\dfrac{5}{12}×\dfrac{3}{10} =$
$\dfrac{1}{8}$

 
$\dfrac{4}{15}÷\dfrac{4}{17} =$
$\dfrac{17}{15}$

$14÷\dfrac{7}{10} =$
20

$\dfrac{1}{4}+\dfrac{13}{24} =$
$\dfrac{19}{24}$

$\dfrac{1}{2}-\dfrac{3}{20} =$
$\dfrac{7}{20}$

$2÷\dfrac{2}{7} =$
7

$\dfrac{39}{45}÷\dfrac{13}{24} =$
$\dfrac{8}{5}$

$\dfrac{1}{6}-\dfrac{2}{13} =$
$\dfrac{1}{78}$

$\dfrac{9}{14}×50\% =$
$\dfrac{9}{28}$

答案

0.8 900 4
542 620 $\dfrac{21}{40}$
$\dfrac{47}{60}$ 2.5 $\dfrac{137}{120}$
400 3.8% 35.4
$\dfrac{1}{8}$ $\dfrac{17}{15}$ 20
$\dfrac{19}{24}$ $\dfrac{7}{20}$ 7
$\dfrac{8}{5}$ $\dfrac{1}{78}$ $\dfrac{9}{28}$
二、解方程或比例。
$\dfrac{4}{5}:x=\dfrac{2}{3}:\dfrac{1}{4}$
$7x + 5.3 = 7.4$
$x + 50\%x + 3.6 = 21.6$
$5x÷\dfrac{2}{3}=5$
$1.2:0.8 = x:1.34$
$x:4=\dfrac{5}{12}:5$

答案

$x=\dfrac{3}{10}$ $x=0.3$ $x=12$
$x=\dfrac{2}{3}$ $x=2.01$ $x=\dfrac{1}{3}$
