    78.5 is . . .

    The number 78.5 . . .

    is not an Integer because it is not a whole number.

    is a Rational number because it can be expressed as the ratio of 2 numbers (157/2)

    is not a Variable because it is a defined constant number.

    is a Constant because it is defined and unchanging number.

    78.5 is a decimal number, and you can transform it in a fraction like:
    785/10.

    78.5 is a constant because its value doesn't change.

    Integers are whole numbers (without decimal point) like -13;35;0;76 and so on.

    A variable is something that changes, the temperature of your room, for instance, the speed of a car etc.

    bye
