Question

Write the following number in base six and in base twelve.

 

Note: Do not use lower-case letters when entering a base twelve number.

 

123 = (_________)six = (__________)twelve

Answer 1

For base six,    123 =  3 x 36 + 2 x 6 + 3   So   123 = 323_six

 

For base 12    123 =  10 x 12 + 3       So   123 =  A3_twelve            (A is the digit representing 10)
