答案的四舍五入
Rounding Answers
解决需要将答案四舍五入到指定精确度的问题。
Solve problems which require answers to be rounded to specified degrees of accuracy
学习证据 / Evidence
- 计算一个除法，并按要求将结果四舍五入到一位小数。
- 确定测量情境中合适的精确度（例如，四舍五入到分）。
- 解决一个需要根据情境解读未四舍五入的小数答案的问题（例如，需要整数个容器）。
- Compute a division and round the result to one decimal place as specified
- Determine the appropriate degree of accuracy for a measurement context (e.g. round to nearest penny)
- Solve a problem where an unrounded decimal answer must be interpreted in context (e.g. whole containers needed)
评估问题 / Assessment
如果{{name}}计算出的答案是8.63，但题目要求四舍五入到最接近的整数，他们能否正确地将它四舍五入为9，并解释为什么在具体情境中这种精确度很重要？
If {{name}} calculates an answer of 8.63 but the question asks for it to the nearest whole number, can they round it correctly to 9 — and explain why that level of precision matters in context?
