Correct Answer(s)
A. 2
B. 3
Explanation
The given answer lists the prime factors of 24, which are 2 and 3. Prime factors are the prime numbers that divide a given number without leaving a remainder. In this case, 2 and 3 are the prime factors of 24 because they are the only prime numbers that can divide 24 evenly.

### Cari hasil tambah faktor perdana bagi 96.

• A.

5

• B.

9

• C.

12

• D.

16

Correct Answer
A. 5
Explanation
The number 96 can be factored into 2^5 * 3. When looking for prime factors, we start with the smallest prime number, which is 2. We divide 96 by 2 and get 48. We continue dividing by 2 until we can no longer divide evenly. In this case, we can divide by 2 five times. So, the prime factorization of 96 includes 2 raised to the power of 5. Therefore, the correct answer is 5.

Rate this question:

• 7.

### Tentukan FSTB bagi 18 dan 54.

• A.

6

• B.

12

18

• D.

Correct Answer
C. 18
Explanation
The given question asks for the FSTB (Faktor Setiap Terkecil Bersama) or the GCF (Greatest Common Factor) of 18 and 54. The FSTB is the largest number that can divide both 18 and 54 without leaving a remainder. To find the FSTB, we can list the factors of both numbers and find the largest number that appears in both lists. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The largest number that appears in both lists is 18, so 18 is the FSTB or GCF of 18 and 54.

Correct Answer
C. 8
Explanation
Bakeri Arisa membuat 24 biji mufin coklat, 32 biji mufin vanila dan 48 biji mufin tiramisu. Jumlah total mufin yang dibuat adalah 24 + 32 + 48 = 104 biji. Setiap bungkusan akan diisi dengan bilangan mufin yang paling banyak, dan bilangan muffin bagi setiap jenis adalah sama banyak. Bilangan muffin yang paling banyak adalah 24, sehingga bilangan bungkusan plastik yang diperlukan adalah 104/24 = 4.33. Karena tidak mungkin memiliki bungkusan plastik sebagian, maka bilangan bungkusan plastik yang diperlukan adalah 4.

F. 18
Explanation
The given sequence consists of multiples of 4, except for the numbers 2 and 18. The numbers 4, 8, 12, 16, and 20 are all multiples of 4 as they can be obtained by multiplying 4 by 1, 2, 3, 4, and 5 respectively. However, the numbers 2 and 18 are not multiples of 4 as they cannot be obtained by multiplying 4 by any whole number. Therefore, the correct answer is 2 and 18.

Explanation
The number 75 is the product of 3 and 25. Since 25 is the square of 5, 75 can be expressed as 3 multiplied by 5 multiplied by 5. Therefore, 75 is the correct answer as it is the multiple of both 3 and 5.

### Aiman menyimpan wang sebanyak RM 1 setiap 8 hari, RM 2 setiap 4 hari dan RM 5 setiap 2 hari. Bilakah dia akan menyimpan duitnya serentak?

• A.

Hari ke-3

• B.

Hari ke-6

• C.

Hari ke-8

• D.

Hari ke-10

Correct Answer
C. Hari ke-8
Explanation
Aiman akan menyimpan duitnya serentak pada Hari ke-8. Pada Hari ke-3, dia hanya menyimpan RM 1 setiap 8 hari, jadi dia belum mencapai hari ke-8 untuk menyimpan duitnya serentak. Pada Hari ke-6, dia menyimpan RM 2 setiap 4 hari, tetapi ini juga belum mencapai hari ke-8. Pada Hari ke-8, dia akan menyimpan RM 1 dan RM 5, karena ini adalah kelipatan dari kedua interval penyimpanannya. Pada Hari ke-10, meskipun dia akan menyimpan RM 2 dan RM 5, ini bukanlah jawaban yang benar karena pertanyaan meminta kapan dia akan menyimpan duitnya serentak.

### Adakah 858 gandaan bagi 6?

• A.

Ya

• B.

Tidak

Correct Answer
A. Ya
Explanation
Ya, 858 adalah gandaan bagi 6. Untuk menentukan apakah suatu angka adalah gandaan bagi angka lain, kita perlu membagi angka tersebut dengan angka lainnya. Jika hasil bagi adalah bilangan bulat, maka angka tersebut adalah gandaan. Dalam kasus ini, jika kita membagi 858 dengan 6, hasilnya adalah 143. Karena hasilnya adalah bilangan bulat, maka 858 adalah gandaan bagi 6.

### Adakah 1 750 gandaan bagi 7?

• A.

Ya

• B.

Tidak

Correct Answer
A. Ya
Explanation
Yes, 1,750 is a multiple of 7 because when we divide 1,750 by 7, we get a whole number without any remainder. In this case, 1,750 divided by 7 equals 250. Therefore, 1,750 is a multiple of 7.

1 dan 2

• B.

1 dan 4

• C.

2 dan 4

• D.

A. 1 dan 2
Explanation
The factors of 86 are 1 and 86, and the factors of 112 are 1, 2, 4, 8, 14, 16, 28, 56, and 112. However, the question asks for the "common factors" of 86 and 112, which means we need to find the factors that both numbers have in common. The only common factors between 86 and 112 are 1 and 2.
