Answer 1

16-15=10000-1111системе1 ,3.9=27,3.9=11.1001 в двоичной сис =11011

Answer 2

16-15=10000-1111(в двоичной системе)=1
3×9=27
3×9=11×1001(в двоичной сис)=11011

Answer 3

Conversion of 16-15 in Binary System

To convert the decimal number 16 to binary, we can use the process of division by 2. Here's how it works:

1. Divide 16 by 2: 16 ÷ 2 = 8, with a remainder of 0. 2. Divide 8 by 2: 8 ÷ 2 = 4, with a remainder of 0. 3. Divide 4 by 2: 4 ÷ 2 = 2, with a remainder of 0. 4. Divide 2 by 2: 2 ÷ 2 = 1, with a remainder of 0. 5. Divide 1 by 2: 1 ÷ 2 = 0, with a remainder of 1.

To convert the remainders into binary, we read them from bottom to top. In this case, the remainders are 0, 0, 0, 0, and 1. Therefore, the binary representation of 16 is 10000.

Now, let's convert the decimal number 15 to binary:

1. Divide 15 by 2: 15 ÷ 2 = 7, with a remainder of 1. 2. Divide 7 by 2: 7 ÷ 2 = 3, with a remainder of 1. 3. Divide 3 by 2: 3 ÷ 2 = 1, with a remainder of 1. 4. Divide 1 by 2: 1 ÷ 2 = 0, with a remainder of 1.

Reading the remainders from bottom to top, we get the binary representation of 15 as 1111.

Therefore, in the binary system, 16-15 is equal to 10000 - 1111.

Calculation of 3×9 in Decimal System

To calculate 3 multiplied by 9 in the decimal system, we simply multiply the two numbers together:

3 × 9 = 27.

Therefore, in the decimal system, 3 multiplied by 9 is equal to 27.
