小數乘法計算題（200道） 5
4樓：哈竹丁詩
1、0.4＋0.4＋0.4＋0.4＋0.4寫成乘法算式是（）。2、計算小數乘法時，先移動因數的小數點，使它變成整數，因數的小數點向右移動幾
位，最後把積的小數點向（
）移動幾位。
3、3.64×1.7的積是（
）位小數，1.16×2.08的積是（
）位小數。
4、根據794×98＝77812，填出下面各式的得數。
79.4×0.98＝（
）79.4×980＝（
）7.94×0.98＝（
）5、小凱做了幾道題，忘記點了小數點，請你幫他點上小數點。
36×2.4＝864
13×0.25＝325
14.4×3.98＝573
126、根據運算律，在
裡填上合適的數。
6.8×2.56＝
×2.5×（1.32×0.4）＝××
5.7×3.8＋4.3×3.8＝(+)×
二、判斷題（對的打「√」錯的打「×」
）（5分）
1、一個因數擴大10倍，另一個因數縮小到它的,積不變。
2、兩個小數相乘，積一定是小數。
3、8.2×9.5的積一定是兩位小數。
4、3.6×1.4＋3.6×8.6＝3.6×（1.4＋8.6）應用的乘法的結合律。
5、0.7×0.7的積用「四捨五入法」保留一位小數約是0.5。
四、在○裡填上「＜」
「＞」或「＝」
（9分）
13.76×0.8○13.76
0.2○1.1×0.2

3.84×2.6≈
5.76×3＝
（保留一位小數）
0.125×1.4≈
14×0.16＝
4.8×0.25＝
（保留兩位小數）
3、脫式計算（能簡算的要簡算）
2.5×7.1×4
16.12×99＋16.12
5.2×0.9＋0.9×4.8
26×15.7＋15.7×24
