A rational number is one such that it is "capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator."
So you must ask yourself: can 2.25 be expressed as a quotient of integers? In other words, can you divide one integer by another and get 2.25? The answer is yes, because 9 divided by 4 is 2.25. Therefore, 2.25 is a rational number.
Yes, 2.25 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers and the denominator is not zero. In this case, 2.25 can be written as the fraction 9/4, where both the numerator (9) and denominator (4) are integers. Therefore, 2.25 is a rational number.
225 is an integer and not a fraction. However, it can be expressed in rational form as 225/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
yes
Yes.
yes
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
Yes, 225 squared is a rational number.
The square root of 225 is 15, which is a rational number.
It is 15 which is a rational number
Yes, 225 squared is a rational number.
yes it is
It is 15.
No because 225 is an integer and all whole numbers are rational
Neither, it is an imaginary number and imaginary numbers are neither rational nor irrational.
-225 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
If you mean the square root of 196/225 then it is 14/15 which is a rational number because it can be expressed as a fraction.
75 times 75 = 5625 which is a rational number
