下午的活动 = aktiviti petang 题目的时间写着 petang，表示下午，属于 p.m.。方法：小时加上十二，分钟照抄，写成四位数，前面加 Jam。写完可以想一想：下午的时间，24 小时制一定在 1200 和 1800 之间左右。 例子：1:40 petang → 1 加 12 得 13 → Jam 1340。 注意：没加 12 会变成凌晨；24 小时制也不会有 24 开头的时间。

an afternoon activity = aktiviti petang The time says petang, which is afternoon, so it is p.m. Add 12 to the hour, copy the minutes, make four digits and write Jam in front. Then check: an afternoon time in the 24-hour system is roughly between 1200 and 1800. Example: 1:40 petang → 1 + 12 = 13 → Jam 1340. Watch out: without adding 12 it becomes early morning, and no 24-hour time starts with 24.

排次序 = susun tertib masa 题目要把几个 24 小时制的时间从早到晚排好。方法：把 Jam 后面的四个数字当成普通的数来比较，数字越小，时间越早；先找最小的放第一，再找第二小的。也可以先说出每个时间是早上、中午还是下午来检查。 例子：Jam 1900、Jam 0830、Jam 1320 → Jam 0830、Jam 1320、Jam 1900。 注意：不要从大排到小，那是从晚到早。

put them in order = susun tertib masa Arrange the 24-hour times from earliest to latest. Compare the four digits after Jam as ordinary numbers: the smaller the number, the earlier the time. Put the smallest first, then the next smallest. You can check by saying whether each is morning, noon or afternoon. Example: Jam 1900, Jam 0830, Jam 1320 → Jam 0830, Jam 1320, Jam 1900. Watch out: ordering from biggest to smallest gives latest to earliest.
