Convert 1AC in hexadecimal into a decimal number.

To convert a hexadecimal number to a decimal number, we multiply each digit by 16 raised to the power of its position (starting from 0 on the right). In the hexadecimal system, the letters A through F represent values 10 through 15.

For the hexadecimal number 1AC:

• C is in the 16⁰ position: 12 × 16⁰ = 12 × 1 = 12
• A is in the 16¹ position: 10 × 16¹ = 10 × 16 = 160
• 1 is in the 16² position: 1 × 16² = 1 × 256 = 256

Adding these values together: 256 + 160 + 12 = 428.

Therefore, 1AC₁₆ is equal to 428₁₀.
