Math Problem Statement
一條絲帶長 五又十分之七 米,媽媽每 八分之五 米剪成一段,最多可剪成多少段?餘下的絲帶長多少米?
Solution
這條絲帶的長度是 米,換算成小數為:
媽媽每 米剪成一段,所以我們需要計算 米可以被 米分割成多少段。這可以透過除法來完成:
所以,最多可以剪成 段,因為我們不能有部分段數。
接下來,我們計算餘下的絲帶長度:
因此,最多可以剪成 段,餘下的絲帶長度為 米。
有需要更多細節或有任何疑問嗎?
相關問題:
- 如何將帶分數轉換為小數?
- 為什麼需要將除法問題轉換為乘法問題?
- 餘數在實際應用中的重要性是什麼?
- 如果絲帶的總長度為 6.5 米,會如何影響結果?
- 有沒有更簡便的方法來計算餘下的絲帶長度?
提示:除法中,分數的倒數與原始數進行相乘可以大幅簡化計算。
