-
11011
-
1010
-
01011
-
01010
Correct Answer
A. 001011Explanation
The given question asks for the binary representation of the decimal number (11)10. To convert a decimal number to binary, we divide the decimal number by 2 and record the remainder until the quotient becomes 0. In this case, when we divide 11 by 2, the remainder is 1 and the quotient is 5. When we divide 5 by 2, the remainder is 1 and the quotient is 2. Finally, when we divide 2 by 2, the remainder is 0 and the quotient is 1. Therefore, the binary representation of (11)10 is 1011.Rate this question:

Bilangan oktal yang benar berikut ini adalah …..
-
8875
-
7581
-
3794
-
2781
-
2561
Correct Answer
A. 2561Explanation
The correct answer is 2561 because it is the only number in the given options that can be represented in octal form. In octal, the digits range from 0 to 7, so any number that contains digits greater than 7 cannot be a valid octal number.Rate this question:

11, 9, 1010
Correct Answer
A. 11, 9, 1010Explanation
The correct answer is 11, 9, 1010. This can be determined by analyzing the given options and finding the pattern that matches the given table. In the table, the first column starts with 9 and increases by 2 for each subsequent row. The second column starts with 7 and alternates between increasing by 1 and decreasing by 3. The third column starts with 1001 and alternates between adding 9 and subtracting 1. Only the option 11, 9, 1010 follows this pattern correctly.Rate this question:

-
1101.10
-
1101.11 d.
Correct Answer
A. 11001.01Explanation
The correct answer is 11001.01. This is because when converting a decimal number to binary, we can follow the process of multiplying the decimal part by 2 and taking the integer part of the result, repeating this process until the decimal part becomes 0. In this case, when multiplying 0.25 by 2, we get 0.5, so the integer part is 0. Then, when multiplying 0.5 by 2, we get 1, so the integer part is 1. This process continues until the decimal part becomes 0. Therefore, the binary representation of 25.25 is 11001.01.Rate this question:

Perbedaan antara pengolahan konversi antara bilangan oktal kebilangan biner dengan konversi antara bilangan hexadesimal kebilangan biner adalah …..
-
Bilangan oktal harus dipisah – pisah lalu diubah ke bilangan biner
-
Bilangan hexadesimal dipisahkan masing-masing digitnya lalu diubah ke bilangan biner dengan jumlah 3 bit
-
Bilangan hexadesimal dipisahkan masing-masing digitnya lalu diubah ke bilangan biner dengan jumlah 4 bit
-
Bilangan oktal dipisahkan masing-masing digitnya lalu diubah ke bilangan biner dengan jumlah 4 bit
-
Tidak ada perbedaan antara konversi bilangan oktal ke biner maupun bilangan hexadesimal ke bilangan biner.
Correct Answer
A. Bilangan hexadesimal dipisahkan masing-masing digitnya lalu diubah ke bilangan biner dengan jumlah 4 bitExplanation
The correct answer states that when converting from hexadecimal to binary, each digit of the hexadecimal number is separated and then converted to binary with a group of 4 bits. This is different from converting from octal to binary, where each digit of the octal number is separated and then converted to binary with a group of 3 bits. Therefore, the difference lies in the number of bits used for the conversion.Rate this question:
