1. 直接写出得数。
3.6×5 = 0.48×5 = 3.6÷0.2 = 0.54 + 0.27 =
3.6×0.5 = 48×5 = 3.6 + 0.2 = 3.09 + 2.8 =
360×5 = 7.4×0.5 = 3.8 - 0.4 = 8.8÷0.8 =
7.4×0.2 = 2.3×0.3 = 0.91×10 = 0.45×0.2 =
7.2÷0.6 = 7.8÷0.3 = 1.8×0.3 = 0.48×0.5 =
3.6×5 = 0.48×5 = 3.6÷0.2 = 0.54 + 0.27 =

2. 解下列方程。
①2x - 3 = 4.8 ②7x + 60 = 158 ③4x - 54 = 14
④32x + 10 = 74 ⑤x - 1.5×0.3 = 3.5 ⑥3.2x - 8 = 19.2
①2x - 3 = 4.8 ②7x + 60 = 158 ③4x - 54 = 14
④32x + 10 = 74 ⑤x - 1.5×0.3 = 3.5 ⑥3.2x - 8 = 19.2
答案:
2. ①$x = 3.9$ ②$x = 14$ ③$x = 17$
④$x = 2$ ⑤$x = 3.95$ ⑥$x = 8.5$
④$x = 2$ ⑤$x = 3.95$ ⑥$x = 8.5$
3. 森林医生。(改错)
①5x - 3.5 + 6.5 = 18.8
解:5x - 10 = 18.8 改正
5x = 8.8
x = 1.76
②3.6 + 0.5x = 5.8
解:0.5x = 3.6 + 5.8 改正
0.5x = 9.4
x = 18.8
①5x - 3.5 + 6.5 = 18.8
解:5x - 10 = 18.8 改正
5x = 8.8
x = 1.76
②3.6 + 0.5x = 5.8
解:0.5x = 3.6 + 5.8 改正
0.5x = 9.4
x = 18.8
答案:
3. ①$5x - 3.5 + 6.5 = 18.8$
解:$5x + 3 = 18.8$
$5x = 15.8$
$x = 3.16$
②$3.6 + 0.5x = 5.8$
解:$0.5x = 2.2$
$x = 4.4$
解:$5x + 3 = 18.8$
$5x = 15.8$
$x = 3.16$
②$3.6 + 0.5x = 5.8$
解:$0.5x = 2.2$
$x = 4.4$
