Yes. According to Wikipedia, "In mathematics, a rational number is any number that can be expressed as the quotient or fraction a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number."
So 28 can be expressed as 28/1, therefore it is a rational number.

Is -28 an integer a rational and a real number?
Yes, -28 is an integer because it is a whole number that can be positive or negative. It is also a rational number because it can be expressed as a fraction, in this case, -28/1. Since any rational number is also a real number, -28 is also a real number.
Is 28 a rational number?

Is the square root of 28 rational or irrational number?
irrational
Is a rational number always a rational number?
As much as, in these days of uncertainty, anything can be anything. As long as the constraints of a rational number are kept to, a rational number will always remain a rational number.
Can you multiply an irrational number and a rational number to get a rational number?
Yes, but only if the rational number is 0.
Is 28 squared rational or irrational?
28 squared is 784 which is a rational number
Is 28 over 5 a rational number?
Yes, 28 over 5 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers. In this case, 28 over 5 can be written as the fraction 28/5, where both 28 and 5 are integers. Therefore, 28 over 5 is a rational number.
Is -28 an integer a rational and a real number?
Yes, -28 is an integer because it is a whole number that can be positive or negative. It is also a rational number because it can be expressed as a fraction, in this case, -28/1. Since any rational number is also a real number, -28 is also a real number.

Is 0.5555 rational or irrational?
0.555 is rational , because it can be converted to a fraction. As given in the question it is a terminating decimal. Hence 0.5555 / 1.0000 Cancel down the decimal point. = 5555/10000 Cancel down by '5' 1111/2000 Is the fraction. However, I think you mean 0.5555.... ( Note the three or more dots , which indicates to mathematicians, that the decimal recurs to infinity. To convert to a fraction. Ler P = 0.5555..... 10P = 5.5555.... Subtract 9P = 5 ( Note ; the recurring decimals subtract to zero). P = 5/9 Hence 0.5555..... = 5/9 NB Decimals that are in a regular order, but recur to infinity, can be converted to a fraction. e.g. 0.123123123..... , or 0.179179179.... and are rational . However, decimals that are in an irregular and recur to infinity, cannot be converted to a fraction. e.g. 0.141592...... are are irrational .
