Points​

Hexadecimal problems use binary.

Steps​

  1. Convert the hexadecimal number to binary. 0.248(16) = 0.0010 0100 1000(2)

  2. Remove the decimal point. 0.0010 0100 1000(2) = 0.0010 0100 1000(2) × 0010 0000 0000(2) / 0010 0000 0000(2) = 0100 1001(2) / 0010 0000 0000(2)

  3. Convert the binary number to decimal. 0100 1001(2) / 0010 0000 0000(2) = (64 + 8 + 1) / 512 = 73 / 512
