一、直接写出得数。
$3.7 + 9.8 =$ $0.9 - 0.26 =$ $2.15 - 1.8 =$
$4.45 - 0.85 =$ $0.3 + 0.47 =$ $0.34 + 1.6 =$
$15.7 + 3 =$ $10 - 0.95 =$ $0.9 - 0.35 =$
$2 - 1.09 =$ $2.53 + 1.64 =$ $76.5 + 4.14 =$
$2.4 - 1.6 =$ $1.5 - 0.6 =$ $0.37 + 1.6 =$
$6.8 - 3.75 =$ $2.2 + 3.57 =$ $6.9 + 5.82 =$
$0.65 + 2.35 =$ $3 - 1.06 =$ $4.13 - 1.57 =$
$0.59 + 0.41 =$ $4.09 - 0.9 =$ $1.3 + 27 =$
$5.5 - 0.08 =$ $3.19 + 3.4 =$ $6.27 - 5.03 =$
$3.7 + 2.12 =$ $5.02 - 3.8 =$ $4.29 + 13.01 =$

答案： 13.5 0.64 0.35
3.6 0.77 1.94
18.7 9.05 0.55
0.91 4.17 80.64
0.8 0.9 1.97
3.05 5.77 12.72
3 1.94 2.56
1 3.19 28.3
5.42 6.59 1.24
5.82 1.22 17.3

二、用竖式计算。
$54 - 38.65$ $19.86 + 7.47$ $40.2 - 27.92$

答案： 15.35 27.33 12.28
