1. 直接写出得数。
$80\times500=$ $2800\div70=$ $460 + 390=$
$1200 - 800=$ $5200 - 2000=$ $25\times400=$
$618\div6=$ $700 + 3000=$ $800 - 170=$
$340 + 660=$ $805\times6=$ $2000\div500=$
$960 - 900=$ $100\div4=$ $630 + 900=$
$37\times40=$ $106 + 886=$ $72\div24=$
$4200\div60=$ $2000 - 300=$ $45\times40=$
$\frac{5}{7}+\frac{1}{7}=$ $1-\frac{5}{8}=$ $\frac{11}{12}-\frac{5}{12}=$
$\frac{5}{6}-\frac{3}{6}=$ $\frac{1}{3}+\frac{1}{3}=$ $\frac{11}{14}-\frac{3}{14}=$
$\frac{7}{9}-\frac{4}{9}=$ $\frac{8}{11}-\frac{3}{11}=$ $\frac{7}{16}-\frac{5}{16}=$
$\frac{7}{10}-\frac{3}{10}=$ $\frac{23}{24}-\frac{11}{24}=$ $1-\frac{1}{8}=$
$\frac{3}{4}+\frac{1}{4}=$ $\frac{7}{18}+\frac{11}{18}=$ $1-\frac{2}{5}=$
$\frac{5}{9}+\frac{3}{9}=$ $\frac{7}{10}+\frac{2}{10}=$ $\frac{11}{24}+\frac{7}{24}=$
$\frac{5}{14}+\frac{3}{14}=$ $1-\frac{21}{22}=$ $\frac{4}{15}+\frac{7}{15}=$
$\frac{13}{23}-\frac{7}{23}=$ $\frac{7}{9}+\frac{2}{9}=$ $\frac{21}{28}-\frac{5}{28}=$
