一、直接写出得数。
$0.68\times100=$ $8\times2.5=$ $6 - 0.5\times2=$
$9.2 - 2.3=$ $0.37 + 0.63=$ $(3.5 + 3.5)\times0.8=$
$0.25\times16=$ $92.5\times0.001=$ $20 - 3.7 - 7.3=$
$1.88 + 1.22=$ $7.56 - 1.4=$ $(1 - 0.1)\times1.01=$
$0.72\times0.2=$ $0.52 + 1.48=$ $1 - 0.6 + 0.4=$
$5.89 + 0.1=$ $200\times4.3=$ $(8.5 - 1.5) - 0.1=$
$7\times2.1=$ $10.62 - 9.3=$ $0.8\times3.98\times1.25=$
$2.4 - 0.06=$ $4.1\times0.3=$ $(2.73 + 3.27)\times0.01=$
$0.36\times0.3=$ $0.54 - 0.04=$ $2.3 + 1.16 + 3.84=$
$2.15 + 0.85=$ $67.08\times0.1=$ $7.85 - 3.06 - 1.94=$

答案： 68 20 5
6.9 1 5.6
4 0.0925 9
3.1 6.16 0.909
0.144 2 0.8
