1. 直接写得数。
8 - 5.8 = 2.6÷0.4 = 0.35÷0.5 = 13.8 - 4.5 =
6.03×3 = 0.5÷100 = 9.5 - 0.64 = 7.9×0.1 =
0.25÷5 = 0.24÷0.4 = 0.16÷5 = 18.3÷0.3 =
3.4×5 = 0.48÷0.12 = 1.25×0.7 = 16.5 - 2.4 =
0.8×1.25 = 5×0.15 = 0.4×0.5 = 8.4 + 1.6 =
3÷0.2 = 12.4÷0.2 = 2.8 + 12.6 = 15.7 - 4.3 =

答案： 2.2 6.5 0.7 9.3
18.09 0.005 8.86 0.79
0.05 0.6 0.032 61
17 4 0.875 14.1
1 0.75 0.2 10
15 62 15.4 11.4

2. 解方程。
7x - 3.4x = 0.72 3 - 0.5x = 0.25 5x + 24 = 8x
0.3x + 1.3×0.2 = 0.62 8x + 4.5 = 6.5 11x + 55 = 165
5.8x - 5x = 12 50x - x = 1029 0.3×3 + 0.2x = 6

答案： $x = 0.2$ $x = 5.5$ $x = 8$
$x = 1.2$ $x = 0.25$ $x = 10$
$x = 15$ $x = 21$ $x = 25.5$

3. 脱式计算，能简算的要简算。
14.7 + 6.36 + 5.3 0.82×101 0.45×2.7 + 0.45×7.3

答案： 26.36 82.82 4.5
