2. KPK dari 20 dan 30 adalah

Explanation

The correct answer is 60 because KPK (Least Common Multiple) is the smallest number that is divisible by both 20 and 30. The factors of 20 are 1, 2, 4, 5, 10, and 20, while the factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The common factors are 1, 2, 5, and 10. To find the KPK, we can multiply the highest power of each common factor, which gives us 2^1 * 5^1 * 10^1 = 60. Therefore, 60 is the KPK of 20 and 30.

4. FPB dari 63 dan 81 adalah

Explanation

The greatest common divisor (GCD) or the highest common factor (HCF) of 63 and 81 is 9. This means that 9 is the largest number that can divide both 63 and 81 without leaving a remainder.

Submit
5. KPK dari 24 dan 18 adalah

Explanation

The correct answer is 72. KPK stands for "Kebalian Persekutuan Terkecil" in Indonesian, which translates to "Least Common Multiple" in English. The least common multiple of 24 and 18 is the smallest number that is divisible by both 24 and 18. To find the least common multiple, we can list the multiples of both numbers and find the smallest number that appears in both lists. The multiples of 24 are 24, 48, 72, 96, 120, 144, ... and the multiples of 18 are 18, 36, 54, 72, 90, 108, 126, 144, .... The smallest number that appears in both lists is 72, so the least common multiple of 24 and 18 is 72.

Submit
6. FPB dari 45 dan 75 adalah

Explanation

The greatest common divisor (GCD) or the highest common factor (HCF) of 45 and 75 is 15. This means that 15 is the largest number that can evenly divide both 45 and 75 without any remainder.

Submit
7. Faktor dari 32 adalah

Explanation

The given answer is correct because it lists all the factors of 32. A factor of a number is a number that divides evenly into that number without leaving a remainder. In this case, 1, 2, 4, 8, 16, and 32 are all numbers that divide evenly into 32.

Submit
8. Bilangan prima diantara 70 dan 80 adalah

Explanation

The correct answer is 71, 73, and 79. These are the prime numbers between 70 and 80. Prime numbers are numbers that are only divisible by 1 and themselves. In this case, 71, 73, and 79 are the only numbers in the given options that meet this criteria. The other options include numbers that are not prime, such as 75 and 77, which are divisible by other numbers besides 1 and themselves.

Submit
9. Kelipatan 6 antara 20 dan 40 adalah

Explanation

The numbers 24, 30, and 36 are all multiples of 6 that fall between 20 and 40. Therefore, they are the correct answer.

Submit
10. kelipatan persekutuan dari 12 dan 16 adalah

Explanation

The given sequence consists of numbers that are multiples of both 12 and 16. The common multiples of 12 and 16 are obtained by finding the least common multiple (LCM) of the two numbers. The LCM of 12 and 16 is 48. Therefore, the sequence starts with 48 and continues with multiples of 48, which are 96, 144, and so on.
