1. 口算。
$460 + 970 =$ $100×3.68 =$ $1000 - 320 =$
$9.23÷10 =$ $4700 - 4000 =$ $0.089×1000 =$
$1000×52.17 =$ $905÷100 =$ $3.6 + 8.4 =$
$600 - 130 =$ $600 + 4000 =$ $3200÷400 =$
$25×40 =$ $750÷25 =$ $14.5 - 6.6 =$
$820 + 560 =$ $96.7 - 90.7 =$ $27×300 =$
$860÷43 =$ $5000 + 5000 =$ $0.6÷10 =$
$16.87×10 =$ $4000×5 =$ $630 + 140 =$
$9500÷1000 =$ $8.1 - 5.4 =$ $100×91.3 =$
$1500 + 2500 =$ $1000÷25 =$ $24.6 - 5.8 =$

2. 在$\bigcirc$里填上“$＞$”“$＜$”或“$=$”。
$4\ dm\bigcirc0.5\ m$ $9.0\ m^{2}\bigcirc0.99$公顷 $7\ t\ 30\ kg\bigcirc7.03\ kg$
$5.8$元$\bigcirc5$元$8$角 $1.9\ dm\bigcirc2.01\ dm$ $2150\ cm^{2}\bigcirc2.15\ m^{2}$
$3.374\bigcirc2.347$ $0.4\bigcirc0.400$ $8\ km\ 900\ m\bigcirc8.9\ km$

答案： ＜@@＜@@＞@@=@@＜@@＜@@＞@@=@@=

3. 用竖式计算。
$108×45 =$ $460×50 =$ $688÷86 =$
