$6.66+0.4=$
$27 \div 1000=$
$5.5-0.05=$
$0.4-\frac{4}{100}=$
$0.6+0.45=$
$1.7-0.25+0.75=$
$4.76 \div 10 \times 100=$
$24 \times 50 \div 1000=$
$1.7-0.25+0.75=$
解 $6.66+0.4=7.06$

$27 \div 1000=0.027$

$5.5-0.05=5.45$

$0.4-\frac{4}{100}=0.36$

$0.6+0.45=1.05$

$1.7-0.25+0.75=2.2$

$4.76 \div 10 \times 100=47.6$ $24 \times 50 \div 1000=1.2$
