Converting the Number 145 from Decimal to Binary (Base 2)

To convert the number 145 from decimal to binary (base 2), we can use the following steps:

1. Divide the decimal number by 2. 2. Write down the remainder (0 or 1). 3. Divide the quotient obtained in step 1 by 2 again. 4. Repeat steps 2 and 3 until the quotient becomes 0. 5. Write down the remainders in reverse order to obtain the binary representation.

Let's apply these steps to convert 145 from decimal to binary:

1. 145 divided by 2 equals 72 with a remainder of 1. 2. 72 divided by 2 equals 36 with a remainder of 0. 3. 36 divided by 2 equals 18 with a remainder of 0. 4. 18 divided by 2 equals 9 with a remainder of 0. 5. 9 divided by 2 equals 4 with a remainder of 1. 6. 4 divided by 2 equals 2 with a remainder of 0. 7. 2 divided by 2 equals 1 with a remainder of 0. 8. 1 divided by 2 equals 0 with a remainder of 1.

Now, let's write down the remainders in reverse order: 10010001.

Therefore, the decimal number 145 is equal to 10010001 in binary.

Converting the Number 145 from Decimal to Octal (Base 8)

To convert the number 145 from decimal to octal (base 8), we can use the following steps:

1. Divide the decimal number by 8. 2. Write down the remainder. 3. Divide the quotient obtained in step 1 by 8 again. 4. Repeat steps 2 and 3 until the quotient becomes 0. 5. Write down the remainders in reverse order to obtain the octal representation.

Let's apply these steps to convert 145 from decimal to octal:

1. 145 divided by 8 equals 18 with a remainder of 1. 2. 18 divided by 8 equals 2 with a remainder of 2. 3. 2 divided by 8 equals 0 with a remainder of 2.

Now, let's write down the remainders in reverse order: 221.

Therefore, the decimal number 145 is equal to 221 in octal.

Converting the Number 145 from Decimal to Hexadecimal (Base 16)

To convert the number 145 from decimal to hexadecimal (base 16), we can use the following steps:

1. Divide the decimal number by 16. 2. Write down the remainder. 3. Divide the quotient obtained in step 1 by 16 again. 4. Repeat steps 2 and 3 until the quotient becomes 0. 5. Write down the remainders in reverse order to obtain the hexadecimal representation. 6. Replace any remainders greater than 9 with the corresponding hexadecimal letters (A, B, C, D, E, F).

Let's apply these steps to convert 145 from decimal to hexadecimal:

1. 145 divided by 16 equals 9 with a remainder of 1. 2. 9 divided by 16 equals 0 with a remainder of 9.

Now, let's write down the remainders in reverse order: 91.

Therefore, the decimal number 145 is equal to 91 in hexadecimal.

In summary: - 145 in binary (base 2) is 10010001. - 145 in octal (base 8) is 221. - 145 in hexadecimal (base 16) is 91.
