Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,100/25恰好是4
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,4×25=100 现在相减 110-100=10
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,4×25=100 相减后得0
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,再落一个0
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,小数点在这儿 写上0.4
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,所以商是4
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,这个分数=0.44
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,那么不必再算下一位了
Dialogue: 0,0:00:00.59,0:00:08.09,Default,,0000,0000,0000,,将分数11/25
Dialogue: 0,0:00:08.09,0:00:11.24,Default,,0000,0000,0000,,也可以说成是25分之11
Dialogue: 0,0:00:11.24,0:00:14.29,Default,,0000,0000,0000,,将它写成小数
Dialogue: 0,0:00:14.29,0:00:17.33,Default,,0000,0000,0000,,并保留到千分位
Dialogue: 0,0:00:17.33,0:00:22.68,Default,,0000,0000,0000,,11/25 也可以看成-
Dialogue: 0,0:00:22.68,0:00:26.50,Default,,0000,0000,0000,,它等价于11÷25
Dialogue: 0,0:00:26.50,0:00:32.22,Default,,0000,0000,0000,,所以这里
Dialogue: 0,0:00:32.22,0:00:35.22,Default,,0000,0000,0000,,可以用11÷25算
Dialogue: 0,0:00:35.22,0:00:39.91,Default,,0000,0000,0000,,得到的就是11/25的
Dialogue: 0,0:00:39.91,0:00:41.53,Default,,0000,0000,0000,,小数形式
Dialogue: 0,0:00:41.53,0:00:44.04,Default,,0000,0000,0000,,因为要保留到的位数在个位之后
Dialogue: 0,0:00:44.04,0:00:45.79,Default,,0000,0000,0000,,要算十分位
Dialogue: 0,0:00:45.79,0:00:49.31,Default,,0000,0000,0000,,百分位 千分位
Dialogue: 0,0:00:49.31,0:00:56.51,Default,,0000,0000,0000,,那么在11后面的小数点后加几个0
Dialogue: 0,0:00:56.51,0:01:00.08,Default,,0000,0000,0000,,开始算除法
Dialogue: 0,0:01:00.08,0:01:08.47,Default,,0000,0000,0000,,1/25除不到
Dialogue: 0,0:01:08.47,0:01:11.69,Default,,0000,0000,0000,,11/25也除不到
Dialogue: 0,0:01:11.69,0:01:23.02,Default,,0000,0000,0000,,110/25可以相除
Dialogue: 0,0:01:23.02,0:01:27.02,Default,,0000,0000,0000,,110/25 4倍 4×25=100
