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.
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.
irrational
The greatest possible remainder is divisor is just less than 28. If the dividend is an integer, then it is 27. But if the dividend is any real number, the greatest possible remainder is 27.999.... (recurring).Strictly speaking, though, the decimal can only be "nearly recurring". This is because 27.999 recurring = 28 and the remainder cannot be 28.The greatest possible remainder is divisor is just less than 28. If the dividend is an integer, then it is 27.

Yes, because it is in the form of terminating decimal...
-28/1000 is one possible answer.
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.
Yes, 28 is an integer.
28 squared is 784 which is a rational number
28.5 = 28 5/10 = 28½ (as a mixed number) 28½ = (28×2+1)/2 = 57/2 (as an improper fraction)
28 is an integer and not a fraction. However, it can be expressed in rational form as 28/1.
Yes because it is repeating and it is a decimal so it is a rational number
28
No, it is irrational
428 is an integer and not a fraction. However, it can be expressed in rational form as 428/1. That is the simplest form. There is no sensible way of writing it as a mixed number.
Yes.
irrational
Yes since 5.6 can be expressed as a fraction (28/5)
