Question

Is -16/-9 a rational number

Answer 1

Answer:

No, the answer (1.77777777778) would be irrational.

Step-by-step explanation:

A rational number is a number that can be expressed as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).

So if we were to solve this problem, we would end up with 1.77777777778

-16/-9 = 1.77777777778

We can now confirm that this number is irrational based on our knowledge of rational numbers and numbers.
