To convert the base 10 number 18 to base 16, we can divide the number by 16 and look for the quotient and the remainder.
- Divide 18 by 16:
- Quotient = 1
- Remainder = 2
So, when we divide 18 by 16, we get a quotient of 1 and a remainder of 2.
In base 16, the number is represented as follows:
- The quotient (1) represents 1×16^1
- The remainder (2) represents 2×16^0
Putting this together, the base 16 representation of the base 10 number 18 is 12.
Therefore, the base 10 number 18 is equal to 12 in base 16.
