《2025年亮点给力计算天天练五年级数学下册苏教版》

一、直接写出得数。（共32分）
0.9 - 0.09 = 0.72 + 1.4 = 13.2÷2 = 2.5×0.79×4 =
0.3÷0.01 = 0.47×2 = 5×2.6 = 0.8×8÷2 =
4.6 + 4 = 55÷0.5 = 0.9 + 0.19 = 0.8×2÷0.1 =
0.42÷1.4 = 4.1 + 14.8 = 16.8÷20 = 3.6÷0.1÷0.4 =
7.56 - 3.12 = 7.5×4 = 8 - 0.87 = 6.2÷3.1÷0.2 =
7.14÷7 = 5.6 + 2.3 = 1.3×40 = 40÷0.5×0.1 =
1.5×0.4 = 4.55÷5 = 2.75 + 32.5 = 8×21×1.25 =
2.1x - 0.9x = 7.1x - 3.1x = 3.4m÷0.5 = 3.95 + 2.4×0.5 =

答案： 0.81 2.12 6.6 7.9
30 0.94 13 3.2
8.6 110 1.09 16
0.3 18.9 0.84 90
4.44 30 7.13 10
1.02 7.9 52 8
0.6 0.91 35.25 210
1.2x 4x 6.8m 5.15

二、在$\square$里填合适的数，使x = 8。（共12分）
$\square$ + x = 22 x - $\square$ = 1.4 0.3x + $\square$ = 3
$\square$ - x = 120 $\square$÷x = 0.4 0.4 + $\square$×x = 10

答案： 14 6.6 0.6
128 3.2 1.2

三、计算下面各题，能简算的要简算。（共9分）
3.68 + 7.56 - 2.68 4×(32.5 - 5.1÷1.7) 91.8×99 + 91.8

答案： 8.56 118 9180

四、解方程。（带☆的要检验）（共21分）
10.98 - x = 0.2×2 2×3.5x = 14 ☆3x - 11.8 = 0.2
☆2x + 1.5x = 42 6x - 5.6 + 9.2 = 19.8 ☆(x + 1.6)÷5 = 3.2

答案： x = 10.58 x = 2 x = 4
x = 12 x = 2.7 x = 14.4
