Bundar Nombor

Untuk membundar kepada puluh terdekat, lihat digit sa. Digit 0 hingga 4 turun, 5 hingga 9 naik.

Langkah 1

Puluh terdekat

Untuk membundar kepada puluh terdekat, lihat digit sa. Digit 0 hingga 4 turun, 5 hingga 9 naik.

Puluh terdekat = 最接近的十
四舍五入到十，要看个位：0 到 4 往下舍，5 到 9 往上进。234 的个位是 4，变成 230；237 的个位是 7，变成 240。
例子：583 个位是 3，舍去得 580；586 个位是 6，进位得 590。
注意：到十看的是个位，不是十位。

Puluh terdekat = Nearest ten
To round to the nearest ten, look at the ones digit: 0 to 4 goes down, 5 to 9 goes up. 234 has 4 ones, so it becomes 230; 237 has 7 ones, so it becomes 240.
Example: 583 rounds down to 580, and 586 rounds up to 590.
Watch out: For the nearest ten, the ones digit decides, not the tens digit.

Langkah 2

Ratus terdekat

Untuk membundar kepada ratus terdekat, lihat digit puluh.

742 → 700 · 768 → 800

Ratus terdekat = 最接近的百
四舍五入到百，要看十位：0 到 4 往下舍，5 到 9 往上进。742 十位是 4，变成 700；768 十位是 6，变成 800。
例子：451 十位是 5，进位得 500；329 十位是 2，舍去得 300。
注意：到百时十位和个位都要变成 0，不要写成 740。

Ratus terdekat = Nearest hundred
To round to the nearest hundred, look at the tens digit. 742 has 4 tens, so it rounds down to 700; 768 has 6 tens, so it rounds up to 800.
Example: 451 rounds up to 500, and 329 rounds down to 300.
Watch out: When rounding to hundreds, both the tens and ones become 0.

Langkah 3

Nombor di tengah dibundar naik

245 berada tepat di tengah antara 240 dengan 250, jadi 245 dibundarkan kepada 250.

Nombor di tengah dibundar naik = 正中间往上进
245 刚好在 240 和 250 正中间，离两边都是 5。规定遇到正中间就往上进，所以 245 变成 250。
例子：650 在 600 和 700 正中间，四舍五入到百得 700。
注意：正中间不往下舍，看到 5 就要进位。

Nombor di tengah dibundar naik = A middle number rounds up
245 sits exactly halfway between 240 and 250, 5 away from each. The rule says a halfway number rounds up, so 245 becomes 250.
Example: 650 is halfway between 600 and 700, so it rounds to 700.
Watch out: A halfway number never rounds down; a 5 always goes up.

Bundarkan 234 kepada puluh terdekat.

Bundarkan 234 = 把 234 四舍五入
这题要把 234 四舍五入到最接近的十。先想 234 前后两个整十，再看个位决定往哪边。选项里有一个是整百，要记得题目要的是十。
例子：412 个位是 2，往下舍得 410。
注意：看个位，不要看十位的 3。

Bundarkan 234 = Round 234
The question asks you to round 234 to the nearest ten. Find the two tens on either side of 234, then let the ones digit decide which way to go. One choice is a whole hundred, so remember the question wants tens.
Example: 412 has 2 ones, so it rounds down to 410.
Watch out: Look at the ones digit, not the tens digit 3.

Bundarkan 267 kepada puluh terdekat.

Bundarkan 267 = 把 267 四舍五入
这题要把 267 四舍五入到十。267 夹在两个整十之间，看个位的大小决定往上还是往下。答案的个位一定是 0。
例子：158 个位是 8，进位得 160。
注意：往上进时十位要加 1，别只把个位改成 0。

Bundarkan 267 = Round 267
The question asks you to round 267 to the nearest ten. 267 lies between two tens, and its ones digit tells you to go up or down. The answer must end in 0.
Example: 158 has 8 ones, so it rounds up to 160.
Watch out: When rounding up, add 1 to the tens digit; do not just change the ones to 0.
