What is 93 in binary?

• 11010011

• 01011101

• 01011100

• 01101101

Answer explanation

Remember, odd numbers end with "1" in binary. If the rightmost bit is "0", the number can't be 93.

The highest order (leftmost) bit is 128 in binary, so if it is a "1" then the number has to be greater than 93.

Convert the binary number 01001011 to decimal.

• 92

• 83

• 75

• 17

Answer explanation

Similar to converting decimal to binary, a number in binary that ends in 1 must be positive. You can rule out any even number.

Similarly, the leftmost bit that is "1" converts to 64, so the number must be greater than that.
