33. A rational number is any number that can be expressed without a fractional part.

Correct Answer: False

A rational number is a number which can be represented in the form of p / q.

34. The base of a number system determines the number of digits used in the system.

Correct Answer: True

35. The digits used in any base are 1 through the base number.

Correct Answer: False

The digits used in any base are 0 through the base number - 1.

39. The number 10 represents the base value in every number system.

Correct Answer: False

The base value of every number system is different.

40. Representing a number in base 5 sometimes requires more digits than representing that same number in base 10.

Correct Answer: True

41. The value of each position in a number system is determined by subtracting the base from the position number.

Correct Answer: False

42. A byte is made up of eight binary digits.

Correct Answer: True

43. Two hexadecimal digits can be stored in one byte.

Correct Answer: True

A hexadecimal digit is a group of four binary digits and a byte is a group of eight binary digit.

44. Starting from the right, every group of four binary digits can be read as one hexadecimal digit.

Correct Answer: True

A hexadecimal digit is a group of four binary digits.

45. To find the decimal equivalent in a new base you just divide the decimal value by the new base.
