5×1.3-2x=5.5 24x+6x=63.6 5.6x+4.4x=5.2
4. 小學數學五年級小數中一個小數怎麼分成整數和小數部分
小數點之前的是整數部分,小數點之後的是小數部分
例如2.8的整數部分是2,小數部分是0.8 ,2.8 = 2 + 0.8
5. 小學五年級上數學 關於小數點的移動
向右移動兩位表示擴大了100倍
就是說原來數是一份,現在數是100份
相差99份,正好相差44.55
所以44.55除以99=0.45【一份就是原來的數】
故原來的數就是0.45
6. 小學數學5年級小數化分數
小數轉化成分數,一位小數就是十分之九、兩位小數就是百分之幾、三位小數就是千分之幾......
如1.2=12/10=6/5;0.7=7/10;0.41=41/100;0.05=5/1000=1/200
