一、口算。
$2.2 + 6.3 = $
8.5
$13.8 - 1.6 = $
12.2
$2.3 + 0.14 = $
2.44

$5.36 + 21 = $
26.36
$4.56 - 4.22 = $
0.34
$4.33 + 5.42 = $
9.75

$0.68 - 0.45 = $
0.23
$4.33 + 4.16 = $
8.49
$4.45 - 2.4 = $
2.05

$0.47 - 0.2 = $
0.27
$10.2 + 4.5 = $
14.7
$0.6 + 8.3 = $
8.9

$3.57 - 1.2 = $
2.37
$7.62 - 2.42 = $
5.2
$1.2 + 5.5 = $
6.7

$1.97 - 0.54 = $
1.43
$7.17 + 1.5 = $
8.67
$3.46 - 3.06 = $
0.4

$0.34 + 10.4 = $
10.74
$9.6 - 3.2 = $
6.4
$5.2 + 7.2 = $
12.4

$15.7 + 3 = $
18.7
$1.6 - 0.8 = $
0.8
$1.9 - 0.26 = $
1.64

答案

一、8.5 12.2 2.44 26.36 0.34 9.75 0.23 8.49 2.05 0.27 14.7 8.9 2.37 5.2 6.7 1.43 8.67 0.4 10.74 6.4 12.4 18.7 0.8 1.64
