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.
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.

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 = 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.
