Sebuah tong berisi 12 ℓ 600 mℓ air sabun. Air itu diisi sama banyak ke dalam 6 botol penyembur. Sebanyak 5 botol digunakan untuk mencuci kereta. Berapakah isi padu air sabun yang digunakan?
一份再几份 = satu bahagian, kemudian beberapa bahagian
先平均分,求出一瓶有多少:总量除以瓶数。题目问的是用了几瓶,所以再用一瓶的量乘用掉的瓶数。算的时候可以先化成毫升,最后化回升和毫升。
例子:9 ℓ 600 mℓ 分成 4 瓶,用了 3 瓶 → 9 600 ÷ 4 = 2 400 → 2 400 × 3 = 7 200 mℓ = 7 ℓ 200 mℓ。
注意:读题时圈出题目最后问的是什么,再决定要算几步。
one share, then several shares = satu bahagian, kemudian beberapa bahagian
First share equally to find how much one bottle holds: the total ÷ the number of bottles. The question asks about the bottles used, so multiply one bottle's amount by the number used. Work in millilitres and change back at the end.
Example: 9 ℓ 600 mℓ shared into 4 bottles, 3 used → 9 600 ÷ 4 = 2 400 → 2 400 × 3 = 7 200 mℓ = 7 ℓ 200 mℓ.
Watch out: circle what the question finally asks before deciding how many steps you need.
8 × 1 ℓ 125 mℓ ÷ 3 = ? mℓ
乘除混合 = darab dan bahagi bergabung
一升一百二十五毫升先化成毫升。按次序先乘八求总量,再除以三求一份。也可以先除后乘检查,两种算法的结果应该一样。
例子:6 × 1 ℓ 50 mℓ ÷ 7 → 6 300 mℓ ÷ 7 = 900 mℓ。
注意:算完以后,可以换一种次序再算一次来检查。
× and ÷ together = darab dan bahagi bergabung
Change 1 ℓ 125 mℓ into millilitres. Multiply by 8 first to get the total, then divide by 3 for one share. You can check by dividing first and multiplying after; both ways should agree.
Example: 6 × 1 ℓ 50 mℓ ÷ 7 → 6 300 mℓ ÷ 7 = 900 mℓ.
Watch out: when you finish, work it out again in the other order to check.
Sebuah kilang kicap mengisi 7 ℓ 200 mℓ kicap sama banyak ke dalam 8 botol. Berapakah isi padu kicap di dalam 3 botol?
几瓶的容量 = isi padu beberapa botol
先求一瓶:总容量化成毫升,除以瓶数。再求三瓶:一瓶的量乘三。最后把毫升写成“几升几毫升”,毫升部分要写成三位数的位置。
例子:5 ℓ 600 mℓ 装 7 瓶,求 2 瓶 → 5 600 ÷ 7 = 800 → 800 × 2 = 1 600 mℓ = 1 ℓ 600 mℓ。
注意:写成升和毫升时,零不能漏掉。
volume of a few bottles = isi padu beberapa botol
First find one bottle: change the total into millilitres and divide by the number of bottles. Then find three bottles: one bottle × 3. Write the result in litres and millilitres, keeping the mℓ in three places.
Example: 5 ℓ 600 mℓ filled into 7 bottles, find 2 bottles → 5 600 ÷ 7 = 800 → 800 × 2 = 1 600 mℓ = 1 ℓ 600 mℓ.
Watch out: do not drop a zero when writing ℓ and mℓ.
Hana mengira 13 ℓ 20 mℓ ÷ 4 = 3 ℓ 5 mℓ. Kiraannya salah. Apakah jawapan yang betul?
升的余数 = baki liter
“几升几毫升”除以一个数时,先除升:如果升有余数,余下的升要化成毫升,和原来的毫升合起来,再继续除,得到的才是毫升的部分。也可以一开始就把全部化成毫升再除。
例子:9 ℓ 40 mℓ ÷ 4 → 2 ℓ 余 1 ℓ → 1 040 mℓ ÷ 4 = 260 mℓ → 2 ℓ 260 mℓ。
注意:升的余数一定要带到毫升那一栏继续除。
a remainder of litres = baki liter
When dividing litres and millilitres, divide the litres first. If litres are left over, change them into millilitres, join them with the millilitres already there, and carry on dividing to find the millilitres. Or change everything into millilitres before dividing.
Example: 9 ℓ 40 mℓ ÷ 4 → 2 ℓ remainder 1 ℓ → 1 040 mℓ ÷ 4 = 260 mℓ → 2 ℓ 260 mℓ.
Watch out: litres left over must be carried into the millilitres and divided.
