Anggar Isi Padu Cecair
Langkah 1

Gunakan bekas rujukan

Bandingkan dengan bekas yang isi padunya diketahui, contohnya satu cawan 250 mℓ.

250mℓ250mℓ250mℓ250mℓ1 000 mℓ= 1 ℓ
bekas rujukan = 参照容器
估液体的量,可以用知道容量的容器来比,例如一杯 250 mℓ。看要估的瓶子大约能倒满几杯。
例子:一个瓶子能倒满 4 杯,估计 250 + 250 + 250 + 250 = 1000 mℓ,也就是 1 ℓ。
注意:每次都要用同一个杯子并倒满,杯子不同就不能这样算。
bekas rujukan = reference container
To estimate an amount of liquid, compare it with a container whose amount you know, such as a 250 mℓ cup. See about how many cupfuls the bottle can fill.
Example: a bottle fills 4 cups, so estimate 250 + 250 + 250 + 250 = 1000 mℓ, which is 1 ℓ.
Watch out: use the same cup filled to the top each time, or the adding does not work.
Langkah 2

Perhatikan saiz dan aras

Bekas lebih besar tidak semestinya mengandungi lebih banyak cecair; lihat juga aras cecair.

saiz bekas + aras cecair
saiz dan aras = 大小和水位
大的容器不一定装的水比较多,还要看水位有多高。一个大瓶只装一点水,可能比一个装满的小杯还少。
例子:大瓶里只有 100 mℓ,小杯装满 250 mℓ,小杯多 250 - 100 = 150 mℓ。
注意:高瘦的瓶和矮胖的碗,装的量可能差不多,别只看高度。
saiz dan aras = size and level
A bigger container does not always hold more liquid; you must also look at how high the liquid reaches.
Example: a big bottle has only 100 mℓ while a full cup has 250 mℓ, so the cup holds 250 - 100 = 150 mℓ more.
Watch out: a tall thin bottle and a short wide bowl may hold about the same, so do not judge by height alone.
Langkah 3

Sukat untuk menyemak

Selepas menganggar, sukat dan buat kesimpulan: kurang daripada, lebih daripada atau hampir tepat.

anggar → sukat → banding
sukat untuk menyemak = 量一量来检查
估完后,小心地把液体倒进量杯,读出实际的量,再和估计值比较。倒的时候要慢,不要洒出来。
例子:估 600 mℓ,量到 550 mℓ,相差 600 - 550 = 50 mℓ。
注意:洒了一些出来,量到的就会比真正的少。
sukat untuk menyemak = measure to check
After estimating, pour the liquid carefully into a measuring jug, read the real amount, and compare it with your estimate. Pour slowly so nothing spills.
Example: estimate 600 mℓ, measure 550 mℓ, and the difference is 600 - 550 = 50 mℓ.
Watch out: any liquid that spills is lost, so the measured amount comes out smaller than the true one.

Cawan rujukan 250 mℓ. Dua cawan serupa dianggar…

dua cawan serupa = 两个一样的杯子
题目说一个参照杯装 250 mℓ,问两个一样的杯子共装多少。方法是把一杯的量加两次。最后检查单位:数字不大时,用 mℓ 还是 ℓ 比较合适。
例子:一杯 200 mℓ,三杯一样的是 200 + 200 + 200 = 600 mℓ。
注意:两个杯子是一样的,所以每杯的量都相同,不用另外猜。
dua cawan serupa = two identical cups
One reference cup holds 250 mℓ, and the question asks how much two identical cups hold together. Add the amount of one cup twice. Then check that the unit makes sense for the size of the number.
Example: one cup holds 200 mℓ, so three identical cups hold 200 + 200 + 200 = 600 mℓ.
Watch out: identical cups each hold the same amount, so there is nothing extra to guess.

Botol sasaran lebih kecil daripada botol 1 ℓ. Anggaran sesuai ialah…

lebih kecil daripada botol 1 ℓ = 比 1 升的瓶子小
题目说要估的瓶子比 1 ℓ 的瓶子小,问合理的估计。比参照小,估计值就要比 1 ℓ 少。记得 1 ℓ 等于 1000 mℓ。
例子:1 ℓ 的瓶倒出 300 mℓ,剩下 1000 - 300 = 700 mℓ。
注意:看到 ℓ 要记得它比 mℓ 大很多,比较前先换单位。
lebih kecil daripada botol 1 ℓ = smaller than a 1 ℓ bottle
The target bottle is smaller than a 1 ℓ bottle, so a sensible estimate must be less than 1 ℓ. Remember that 1 ℓ equals 1000 mℓ, and change every choice to the same unit before comparing.
Example: pour 300 mℓ out of a 1 ℓ bottle and 1000 - 300 = 700 mℓ is left.
Watch out: a number with ℓ is much more than the same number with mℓ.
