一、口算。
$17.5 - 7.2 = $
10.3
$0.66 + 5.4 = $
6.06
$3 - 0.25 = $
2.75

$19.5 - 3.5 = $
16
$2.37 + 1.3 = $
3.67
$3.5 - 2.5 = $
1

$0.5 + 0.35 = $
0.85
$1.35 - 0.3 = $
1.05
$32.8 - 1.8 = $
31

$5.2 + 1.08 = $
6.28
$3.2 + 1.68 = $
4.88
$2.8 - 0.4 = $
2.4

$14 - 7.6 = $
6.4
$1.92 - 0.09 = $
1.83
$1.4 + 0.32 = $
1.72

$0.6 - 0.06 = $
0.54
$0.75 + 1.4 = $
2.15
$0.4 + 0.9 = $
1.3

$0.3 + 1.54 = $
1.84
$0.8 + 0.07 = $
0.87
$10 - 9.12 = $
0.88

$2.03 + 3.7 = $
5.73
$1 - 0.01 = $
0.99
$5.4 - 2.8 = $
2.6

答案

一、10.3 6.06 2.75
16 3.67 1
0.85 1.05 31
6.28 4.88 2.4
6.4 1.83 1.72
0.54 2.15 1.3
1.84 0.87 0.88
5.73 0.99 2.6
二、用竖式计算。
$16 - 7.35$ $9.5 - 3.67$ $10.03 - 8.32$
 
$10.67 - 6.7$ $12.37 - 4.83$ $100.4 - 2.76$

答案


二、8.65 5.83 1.71
3.97 7.54 97.64
