周和天除以数 = bahagi minggu dan hari 先除周，商写在周那一栏；余下的周换成天（每周七天），加上原来的天数，再除以除数得到天。 例子：9 周 1 天 ÷ 4 → 2 周余 1 周 → 7 + 1 = 8 天 ÷ 4 = 2 天 → 2 周 2 天。 注意：换成天以后，别忘了加上原来就有的天数。

dividing weeks and days = bahagi minggu dan hari Divide the weeks first and write the quotient in the weeks column. Change leftover weeks into days (7 each), add the days already there, then divide to get the days. Example: 9 weeks 1 day ÷ 4 → 2 weeks remainder 1 week → 7 + 1 = 8 days ÷ 4 = 2 days → 2 weeks 2 days. Watch out: after changing to days, remember to add the days that were already there.

abad 和年除以数 = bahagi abad dan tahun 先除 abad，商写在 abad 那一栏；余下的 abad 换成年（每个一百年），加上原来的年数，再除以除数，得到年。 例子：5 abad ÷ 2 → 2 abad 余 1 abad → 100 年 ÷ 2 = 50 年 → 2 abad 50 年。 注意：只把原来的年数除以除数，会漏掉余下的 abad。

dividing centuries and years = bahagi abad dan tahun Divide the abad first and write the quotient in the abad column. Change leftover abad into years (100 each), add the years already there, then divide to get the years. Example: 5 abad ÷ 2 → 2 abad remainder 1 abad → 100 years ÷ 2 = 50 years → 2 abad 50 years. Watch out: dividing only the years that were given leaves out the leftover abad.

天除以数 = bahagi hari 题目只有天，答案要写成几天几小时。先用天数除以除数，商是天；余下的天换成小时（乘二十四），再除以除数，得到小时。 例子：9 天 ÷ 4 → 2 天余 1 天 → 24 小时 ÷ 4 = 6 小时 → 2 天 6 小时。 注意：余数是天，不是小时，要先换成小时才可以再除。

dividing days = bahagi hari The question has only days, but the result must be written in days and hours. Divide the days first; the quotient is days. Change the leftover days into hours (× 24) and divide again to get the hours. Example: 9 days ÷ 4 → 2 days remainder 1 day → 24 hours ÷ 4 = 6 hours → 2 days 6 hours. Watch out: the remainder is in days, not hours; change it into hours before dividing.

平均分时间 = bahagi masa sama rata 每件衣服用的时间一样，所以用总天数除以件数。先除天，商是天；余下的天换成小时，再除以件数，得到小时。答案写成几天几小时。 例子：10 天做 4 个 → 2 天余 2 天 → 48 小时 ÷ 4 = 12 小时 → 2 天 12 小时。 注意：余数是天，一定要换成小时再除。

sharing time equally = bahagi masa sama rata Each piece takes the same time, so divide the total days by the number of pieces. Divide the days first; the quotient is days. Change the leftover days into hours and divide again to get the hours. Example: 4 items in 10 days → 2 days remainder 2 days → 48 hours ÷ 4 = 12 hours → 2 days 12 hours. Watch out: the remainder is in days and must be changed into hours before dividing.
