(ii) Nyatakan bilangan tin minuman dan (c) Sekotak pen boleh dibahagi sama rata
bungkus keropok dalam setiap beg. kepada 15 orang murid, 30 orang murid atau
State the numbers of canned drinks and packets of 40 orang murid. Cari bilangan terbesar pen
crackers in each bag. yang ada dalam kotak itu.
[2 markah / 2 marks] A box of pens can be divided equally to 15 students, 30

Jawapan / Answer : students or 40 students. Find the largest possible number
Bilangan tin minuman of pens in the box.
Number of canned drinks [3 markah / 3 marks]
= 16 ÷ 8 Jawapan / Answer :
= 2
5 15 , 30 , 40
Bilangan bungkus keropok 2 3 , 6 , 8
Number of packets of crackers 3 3 , 3 , 4
= 24 ÷ 8
= 3 4 1 , 1 , 4
1 , 1 , 1

(b) Terdapat 3 bongkah kayu, dengan panjang GSTK bagi 15, 30 dan 40
masing-masing ialah 6 cm, 9 cm dan 12 cm. LCM of 15, 30 and 40
Aden hendak memotong kesemua bongkah = 5 × 2 × 3 × 4
kayu tersebut menjadi bongkah kayu kecil = 120
dengan panjang yang sama.
There are 3 wooden blocks, with length of 6 cm, 9 cm and Maka, bilangan terbesar pen yang ada dalam
12 cm respectively. Aden wants to cut all of the wooden
blocks into small wooden blocks of equal length. kotak itu ialah 120 batang.
Hence, the largest possible number of pens in the box is
Setelah semua bongkah kayu dipotong, 120.
After all of the wooden blocks were cut,
(i) berapakah panjang maksimum bagi
satu bongkah kayu kecil?
what is the maximum length of a small wooden
block? 8. (a) Rajah di bawah menunjukkan gandaan 8
(ii) berapakah bilangan bongkah kayu kecil dan gandaan 12.
yang Aden ada? The diagram below shows the multiples of 8 and
how many small wooden blocks that Aden has? multiples of 12.
[3 markah / 3 marks] Nombor Gandaan
Jawapan / Answer : Number Multiples
8 8, 16, 24, 32, 40, 48, …
(i) 3 6 , 9, 12
2 , 3, 4 12 12, 24, 36, 48, 60, 72, …

FSTB / HCF = 3 (i) Nyatakan dua gandaan sepunya
Setiap bongkah kayu kecil mempunyai pertama bagi 8 dan 12.
panjang maksimum 3 cm. State the first two common multiples of 8 and 12.
Each small wooden block has maximum length of [1 markah / 1 mark]
3 cm.
Jawapan / Answer :
24, 48

(ii) (6 ÷ 3) + (9 ÷ 3) + (12 ÷ 3) (ii) Nyatakan gandaan sepunya terkecil
= 2 + 3 + 4 bagi 8 dan 12.
= 9 State the lowest common multiple of 8 and 12.
[1 markah / 1 mark]
Aden mempunyai 9 bongkah kayu kecil. Jawapan / Answer :
Aden has 9 small wooden blocks. 24
