1. 直接写得数。
11.6 + 2.3 = 5.2×0.3 = 6.12×0.4 = 6.8÷0.4 =
11.6×5 = 2.7 + 3.6 = 40.5÷5 = 2.4×0.6 =
0.396÷0.6 = 7.56÷9 = 8.7÷0.5 = 3.7 + 3.8 =
1.02 + 1.03 = 5×0.24 = 96÷2.4 = 6 + 6.6 =
1.44÷12 = 7.3×0.2 = 0.78 - 0.14 = 1.34 + 0.7 =
7.2 - 0.4 = 3.4×0.2 = 2.8÷0.08 = 0.32×5 =
11.6 + 2.3 = 5.2×0.3 = 6.12×0.4 = 6.8÷0.4 =
11.6×5 = 2.7 + 3.6 = 40.5÷5 = 2.4×0.6 =
0.396÷0.6 = 7.56÷9 = 8.7÷0.5 = 3.7 + 3.8 =
1.02 + 1.03 = 5×0.24 = 96÷2.4 = 6 + 6.6 =
1.44÷12 = 7.3×0.2 = 0.78 - 0.14 = 1.34 + 0.7 =
7.2 - 0.4 = 3.4×0.2 = 2.8÷0.08 = 0.32×5 =
答案:
13.9 1.56 2.448 17 58 6.3 8.1 1.44 0.66 0.84 17.4 7.5 2.05 1.2 40 12.6 0.12 1.46 0.64 2.04 6.8 0.68 35 1.6
2. 解方程。
x - 0.7x = 3.6 x + 2x + 18 = 78 18(x - 3) = 270
6x - 12.8×3 = 0.06 1.4×8 - 2x = 6 (200 - x)÷5 = 30
10.5 + x + 22 = 55 4(x - 5.6) = 3.2 (0.5 + x) + x = 7.8÷2
x - 0.7x = 3.6 x + 2x + 18 = 78 18(x - 3) = 270
6x - 12.8×3 = 0.06 1.4×8 - 2x = 6 (200 - x)÷5 = 30
10.5 + x + 22 = 55 4(x - 5.6) = 3.2 (0.5 + x) + x = 7.8÷2
答案:
$x = 12$ $x = 20$ $x = 18$ $x = 6.41$ $x = 2.6$ $x = 50$ $x = 22.5$ $x = 6.4$ $x = 1.7$
3. 脱式计算,能简算的要简算。
4.3×2.1 - 7.6 12.5 - (1.9 + 6.5) 7.5×16.3 + 7.5×3.7
4.3×2.1 - 7.6 12.5 - (1.9 + 6.5) 7.5×16.3 + 7.5×3.7
答案:
1.43 4.1 150
