一、口算。
$3.65 + 0.74 = $

4.39

$7.8 ÷ 0.13 = $

$18.9 - 2.37 = $

16.53

$30.2 × 60 = $

1812

$12 ÷ 0.24 = $

$4.5 ÷ 0.6 = $

7.5

$12.12 ÷ 6 = $

2.02

$3.04 - 1.4 = $

1.64

$0.396 ÷ 3.96 = $

0.1

$7 - 0.75 = $

6.25

$0.4 × 12.5 = $

$9.5 ÷ 0.5 = $

$18.6 ÷ 0.6 = $

$4.8 + 0.48 = $

5.28

$51 ÷ 1.7 = $

$32 ÷ 0.32 = $

100

$0.16 + 0.54 = $

0.7

$125 × 0.8 = $

100

$3.12 × 30 = $

93.6

$0.42 ÷ 35 = $

0.012

$0.68 + 0.42 = $

1.1

$3.4 ÷ 0.02 = $

170

$5.3 × 0.3 = $

1.59

$40 ÷ 0.25 = $

160

答案

4.39 60 16.53 1812 50 7.5 2.02 1.64 0.1 6.25 5 19 31 5.28 30 100 0.7 100 93.6 0.012 1.1 170 1.59 160
