Soalan 1 / 7Latihan tambahan
Bundarkan 91 507 kepada ribu terdekat.
看到 5 = digit 5 题目要取整到最接近的千,所以看百位。规则:0 到 4 不变,5 到 9 进位;刚好是 5 时,也属于进位的那一边。决定好以后,千位右边全部写 0。 例子:6 520 取整到千 → 百位 5 → 千位加 1 → 7 000。 注意:“5”常被当成不变,这是最常见的错;也不要看成取整到万。
a digit of 5 = digit 5 Round to the nearest thousand, so look at the hundreds digit. The rule is 0 to 4 stay, 5 to 9 round up, and exactly 5 rounds up. Then every place to the right of the thousands becomes 0. Example: 6 520 has 5 hundreds, so it rounds up to 7 000. Watch out: treating 5 as stay the same is the most common mistake, and do not round to ten thousands by accident.
Soalan 2 / 7Latihan tambahan
Berapakah RM45 099 jika dibundarkan kepada puluh ribu ringgit yang terdekat?
金额取整到万 = bundar wang kepada puluh ribu 钱的取整方法和普通数一样,只是前面保留 RM。题目要取整到最接近的万令吉,所以看千位:0 到 4 万位不变,5 到 9 万位加 1;最后万位右边全部写 0。 例子:RM12 800 → 千位 2 → RM10 000;RM17 300 → 千位 7 → RM20 000。 注意:取整到万的结果后四位都是 0;答案前面别忘了 RM。
round money to ten thousands = bundar wang kepada puluh ribu Money is rounded like any number; keep the RM in front. For the nearest ten thousand ringgit, look at the thousands digit: 0 to 4 keep, 5 to 9 add 1, then all places to the right become 0. Example: RM12 800 has 2 thousands, so it becomes RM10 000; RM17 300 becomes RM20 000. Watch out: a result rounded to ten thousands ends in four zeros, and keep the RM.
Soalan 3 / 7Latihan tambahan
Bundarkan 3 961 kepada ratus terdekat.
连续进位 = kumpul semula ke tempat ribu 题目要取整到最接近的百,所以看十位决定百位要不要加 1。如果百位原来是 9,再加 1 就变成 10:百位写 0,向千位进 1。最后十位和个位都写 0。 例子:6 972 取整到百 → 十位 7 → 百位 9 + 1 = 10 → 7 000。 注意:进位以后千位也会改变;取整到百和取整到十的答案不同,看清题目。
rounding with regrouping = kumpul semula ke tempat ribu Round to the nearest hundred, so the tens digit decides whether to add 1 to the hundreds. If the hundreds digit is 9, adding 1 makes 10: write 0 in the hundreds and carry 1 to the thousands. Then the tens and ones become 0. Example: 6 972 has 7 tens, so 9 hundreds + 1 = 10 and it becomes 7 000. Watch out: the carry changes the thousands too, and rounding to hundreds is not rounding to tens.
Soalan 4 / 7Latihan tambahan
Selepas dibundarkan kepada ribu terdekat, nombor manakah menjadi 18 000?
范围 = julat 题目问哪个数取整到千后会变成指定的整千。先写出范围:从下面的“正中间的数”开始,到上面“正中间的数”减 1 为止。再用百位检查每个选项:在范围里的才对。 例子:取整到千变成 5 000 的数,范围是 4 500 到 5 499;4 620 可以,4 480 不行。 注意:离边界只差几十的数最容易看错;在范围外的数会变成相邻的另一个整千。
range = julat Which number becomes the given thousand after rounding? Write the range from the halfway number below to one less than the halfway number above, then check each option. Example: numbers that round to 5 000 run from 4 500 to 5 499, so 4 620 works and 4 480 does not. Watch out: numbers just a few tens from an end are easy to misjudge; outside the range they round to a neighbouring thousand.

Sebuah kilang menghasilkan 52 700 biji tin. Bundarkan kepada puluh ribu terdekat.
取整到万 = bundar kepada puluh ribu terdekat 题目是生活情境,要把工厂的产量取整到最接近的万。先确认要取整的是万位,再看千位决定进位或不变,最后万位右边全部写 0。 例子:73 400 取整到万 → 千位 3 → 70 000;取整到千则是 73 000。 注意:题目要的是万,不是千;取整到千和取整到万的答案不一样。
round to the nearest ten thousand = bundar kepada puluh ribu terdekat Round the factory's output to the nearest ten thousand. Confirm the rounding place is the ten thousands, use the thousands digit to decide, then make every place to the right 0. Example: 73 400 to the nearest ten thousand is 70 000, but to the nearest thousand it is 73 000. Watch out: the question asks for ten thousands, not thousands, and the two answers are different.
Soalan 6 / 7Latihan tambahan
Siapakah betul? Bundarkan 44 999 kepada puluh ribu terdekat.
只看一位 = lihat satu digit sahaja 三个人把同一个数取整到最接近的万,答案不同,要判断谁对。取整到万时只看千位:0 到 4 不变,5 到 9 加 1;千位后面的数字不管多大,都不会让千位先进位。 例子:14 999 取整到万 → 千位 4 → 10 000;15 000 才会变成 20 000。 注意:取整不是从个位开始一步一步往前进位;结果必须是整万。
look at one digit = lihat satu digit sahaja Three pupils rounded the same number to the nearest ten thousand. Only the thousands digit decides: 0 to 4 stay, 5 to 9 add 1. The digits after it never carry into the thousands first. Example: 14 999 has 4 thousands, so it becomes 10 000; only 15 000 and above round to 20 000. Watch out: rounding does not carry step by step from the ones, and the result must be a whole ten thousand.
Soalan 7 / 7Latihan tambahan
Aida memilih tiga nombor. Setiap nombor dibundarkan kepada puluh ribu terdekat, dan hasilnya 70 000. Set manakah sesuai?
举出取整的数 = beri nombor yang dibundarkan 题目要找出“三个数都会取整成指定整万”的那一组。先写出范围:从下面的正中间数开始,到上面的正中间数减 1 为止。再检查每一组的三个数,三个都在范围里,这一组才对;只要有一个在范围外就不行。 例子:取整到万变成 20 000 的范围是 15 000 到 24 999;检查 16 400、21 080、25 300 这一组:25 300 在范围外,所以这一组不行。 注意:边界上的数要特别小心:下边界本身在范围里,上边界再多 1 就会变成下一个整万。
give numbers that round = beri nombor yang dibundarkan Find the set where all three numbers round to the given ten thousand. Write the range from the halfway number below to one less than the halfway number above, then check every number in each set; one number outside the range spoils the set. Example: numbers that round to 20 000 run from 15 000 to 24 999; in the set 16 400, 21 080, 25 300 the last number is outside the range, so the set fails. Watch out: take care at the ends; the lower end is inside the range, but one more than the upper end rounds to the next ten thousand.
