Explanation:
I'm assuming you mean is the number 90 a rational number. The answer is that yes, it is a rational number.
Let me explain:
Under all the possible numbers, there is a taxonomy to organize these types of numbers. It goes down a list from:
- all numbers, which is divided into two groups; complex and real
Under real numbers, there's rational and irrational:
Under rational, there's integers and fractions
Under integers, there's whole numbers and negative
Under whole numbers, there's natural numbers and 0 (yes, zero).
90 falls under natural numbers, which means it is also a rational number. Hope this helps!
