Question

Is 1/999 rational or irrational

Answer 1

Answer: Rational

========================================================

Reason:

Any rational number is a fraction of two integers. In this case, the two integers are 1 and 999.

Other examples of rational numbers include the following:

• 2/3
• 6/17
• -1/4
• -55/92

Pick any two of your favorite integers on the number line, then divide them to form a fraction. That will form a rational number. The two numbers you pick could be positive or negative.

Note: you can never have 0 in the denominator. Dividing by zero is not allowed. Try out something like 2/0 in your calculator and it will say "undefined", "not a number", "NaN", or "error".
