2025年通城学典计算能手五年级数学上册苏教版第91页答案
一、口算。
$2.8×0.4= $
1.12
$0.1 - 0.01 = $
0.09
$1.5 - 1.5×0.2 = $
1.2

$0.84÷0.06 = $
14
$5.1÷0.17 = $
30
$1.5÷0.3×0.4 = $
2

$1.24×5 = $
6.2
$7.2×0.3 = $
2.16
$8.1÷3×2 = $
5.4

$19.3 - 2.7 = $
16.6
$0.77 + 0.33 = $
1.1
$1.9×4×0.5 = $
3.8

$2.5×1.8 = $
4.5
$7.28÷0.8 = $
9.1
$0.99×9 + 0.99 = $
9.9

$0.18÷0.2 = $
0.9
$9 - 2.9 = $
6.1
$1.8÷4÷0.5 = $
0.9

$60×0.03 = $
1.8
$0.5÷100 = $
0.005
$3.2 - 1.34 - 1.66 = $
0.2

$85.2 - 3.25 = $
81.95
$12.6÷0.6 = $
21
$3×0.5 - 1 = $
0.5

答案

1.12 0.09 1.2 14 30 2 6.2 2.16 5.4 16.6 1.1 3.8 4.5 9.1 9.9 0.9 6.1 0.9 1.8 0.005 0.2 81.95 21 0.5
二、用竖式计算。
$4.37 - 2.49$ $0.48÷3.2$ $1.82×0.45$

$1.48 + 2.59$ $3.5×2.58$ $54.61÷0.127$

答案

1.88 0.15 0.819 4.07 9.03 430
