Question

christopher claims that 4 is not a rotional number because it is not writtwn as a ratio of integers. Is he correct? Explain why or why not

Answer 1

Christopher is incorrect. The value 4 is a rational number because
4 = 4/1
We can write 4 as a ratio or fraction of whole numbers. So this is why it's rational.

Note: the denominator or value in the bottom cannot be 0

another note: any whole number or integer is a rational number because we can use the trick shown above. Simply place the value over 1
(other examples: 7 = 7/1, 22 = 22/1, etc)
