几周几天化天 = minggu dan hari ke hari 先把“周”的部分乘七换成天，再加上题目里原来就有的天数，两部分合起来才是总天数。 例子：1 周 6 天 → 7 + 6 = 13 天。 注意：常见错误是只换了周，却忘了加后面的天；也不要把周和天的数字直接拼在一起。

weeks and days to days = minggu dan hari ke hari Change the weeks part into days by multiplying by 7, then add the days already given. The two parts together are the total days. Example: 1 week 6 days → 7 + 6 = 13 days. Watch out: do not stop after changing the weeks and forget the days, and do not just join the two numbers together.

天化周 = hari ke minggu 问“有几周”，就是问天数里有几个七，用除法：天数除以七。如果刚好除尽，答案只有周，没有余下的天。可以用乘法验算：周数乘七应该回到原来的天数。 例子：70 天 → 70 ÷ 7 = 10 周。 注意：不能把两位数的数字拆开来当作周和天。

days to weeks = hari ke minggu Asking how many weeks means asking how many 7s are in the days: divide by 7. If it divides exactly, the result is only weeks. Check by multiplying: weeks × 7 should give the days again. Example: 70 days → 70 ÷ 7 = 10 weeks. Watch out: do not split the two digits into weeks and days.

假期有几周几天 = tempoh cuti 题目给的是总天数，要写成“几周几天”。先用七的乘法表找出最多有几个七天，这是周数；再用总天数减去这些天，剩下的是天数。 例子：45 天 → 6 × 7 = 42，45 − 42 = 3 → 6 周 3 天。 注意：减完之后要检查余下的天是不是少于七。

weeks and days of a holiday = tempoh cuti The question gives total days to be written as weeks and days. Use the 7 times table to find the most whole 7s (the weeks), then subtract those days from the total to get the days left. Example: 45 days → 6 × 7 = 42, 45 − 42 = 3 → 6 weeks 3 days. Watch out: after subtracting, check that the days left are fewer than 7.
